Pay for the prepared Rampant Growth to find a basic land. The Bear stays on the battlefield after you cast that copy.
The set’s mechanics with worked examples, then every word on the cards.
A prepared creature gives you a copy of its inset spell in exile. Cast the copy, pay its cost, and the creature becomes unprepared.

Pay for the prepared Rampant Growth to find a basic land. The Bear stays on the battlefield after you cast that copy.
These abilities reward casting an instant or sorcery that targets a creature. Each card supplies its own reward.

Cast a creature-targeting instant or sorcery while the Duelist is in play to trigger its repartee ability before that spell resolves.
Casting an instant or sorcery triggers opus. Spending at least five mana to cast that spell upgrades the result.

Compare a cheap spell with a spell costing five or more actual mana: the Stallion’s printed reward changes with what you spent.
Infusion checks whether you gained life earlier in the current turn. The amount and your net life change do not matter.

Attack with a Pest to gain life before casting Educator in your second main phase and receiving its counters.
Cast a card from your graveyard for its flashback cost, then exile it when it leaves the stack.

The eight-mana flashback cost produces eight damage if all eight mana were spent; it also meets opus and can trigger increment.
After you cast a spell, this creature grows if the mana you spent is greater than its power or its toughness.

A sufficiently expensive spell puts a counter on Colony. Its next increment may require more mana because it has grown.
The first resolved paradigm spell of a name is exiled and lets you cast a free copy at the beginning of each of your future first main phases.

Resolve Capstone once, then get a new chance to cast its copy each of your turns without paying its mana cost.
Converge counts how many different colors of mana were spent to cast the spell, from zero to five.

Use genuinely different colors of mana to increase its converge result, while keeping a mana base that can cast your other spells.
Book is an artifact subtype. Read each Book’s abilities; the subtype itself grants no shared activated ability.

Diary is a Book, and its own rules text tells you how to use it.
The set’s Pest tokens gain life when they attack. Fractals begin as 0/0 creatures and rely on the counters supplied by their creating effect.

Pest Friend creates a Pest with an attack trigger. This differs from the dies-to-gain-life Pest tokens of the original Strixhaven set.
Every word on the cards and in the deck plans, defined once. Find a term, read its wording, then see it on a card.
A +1/+1 counter adds one power and one toughness; a −1/−1 counter subtracts one of each. These counters stay until removed or the object changes zones.
Watch out: If a permanent has both kinds, matching pairs are removed as a state-based action. A temporary +1/+1 effect is not a counter.
Reduce the generic part of this spell’s cost by one for each permanent of the specified kind you control.
Watch out: It does not reduce the colored mana symbols. Check exactly what the card has affinity for.
When you cast the spell, exile cards until you find a cheaper nonland card. You may cast it free only if the resulting spell is also cheaper. Put the other exiled cards on the bottom randomly. Cascade triggers before the original spell resolves.
Converge counts how many different colors of mana were spent to cast the spell, from zero to five.
While paying for this spell, each untapped creature you tap can cover one generic mana, or one mana of that creature’s color.
Watch out: You may tap a creature you just played. A colorless creature can cover only generic mana.
To counter a spell or ability is to remove it from the stack without its effects resolving. A countered spell normally goes to its owner’s graveyard.
Watch out: This use of “counter” is different from placing a marker such as a +1/+1 counter on a card.
Tap other untapped creatures you control with enough total power to turn this Vehicle into an artifact creature until the turn ends.
Watch out: The crew creatures do not become the Vehicle’s attackers. A newly played Vehicle still needs haste to attack that turn.
A mix of costs that lets you use your mana on early and late turns.
From your hand, pay the cycling cost and discard this card to draw a card.
Watch out: Cycling is an activated ability, not casting the card. Typecycling searches for a specified kind of card instead.
Any positive amount of damage this source deals to a creature is enough to make that damage lethal.
Watch out: It works with a fight or other noncombat damage. Indestructible still prevents destruction.
Move a permanent from the battlefield to its owner’s graveyard because an effect or lethal damage destroys it.
Watch out: Indestructible stops destruction. Sacrificing, exiling, and reducing toughness to 0 are different ways for a creature to leave.
Move a card from your hand to your graveyard.
Watch out: Discarding is not casting. It does not pay the card’s mana cost or produce its normal spell effect.
Doubling counters adds as many of that kind as are already there. Doubling power gives a modifier based on the creature’s power when the effect resolves; it does not necessarily change base power or add counters.
This creature deals combat damage in the first-strike damage step and again in the normal damage step if it is still in combat.
Watch out: If its blocker dies in the first step, a blocked attacker does not hit the player in the second step unless an ability such as trample allows it.
Move the object to the exile zone. It is separate from the graveyard.
Watch out: A card in exile cannot normally be played. You need a rule or effect giving permission, such as a resolved Adventure.
This label points to an ability that cares about controlling a creature with power 4 or greater.
Watch out: The timing and benefit come from the rest of the printed ability. The word itself adds no rules.
The two creatures each deal damage equal to their power to the other at the same time.
Watch out: This is not combat. First strike and double strike do not add damage steps; deathtouch and lifelink still affect damage.
This creature deals combat damage in an earlier step, before creatures without first strike or double strike.
Watch out: A creature killed in that early damage step usually cannot deal its normal combat damage.
You may cast this spell when you could cast an instant, including during another player’s turn when you have priority.
Watch out: Flash changes when you may cast it. It does not let you cast from a different zone or avoid its costs.
You may cast this instant or sorcery from your graveyard by paying its flashback cost.
Watch out: Follow its normal timing. A spell cast with flashback is exiled when it leaves the stack, even if it is countered.
Cast a card from your graveyard for its flashback cost, then exile it when it leaves the stack.
An attacking creature with flying can be blocked only by creatures with flying or reach.
Watch out: A flying creature can block a creature without flying.
Grandeur marks an ability paid for by discarding another card with the specified name. Read the individual card for its effect; the copy already on the battlefield is not the card you discard.
This creature may attack and use abilities with the tap or untap symbol even if you have not controlled it since your turn began.
Watch out: It still needs to be untapped to attack or pay a tap cost.
A permanent with hexproof cannot be targeted by spells or abilities its controller’s opponents control.
Watch out: Its controller may target it. Effects that do not target can still affect it.
Each split mana symbol can be paid using either half. For example, {W/U} costs one white or one blue mana; {2/B} costs two mana of any type or one black mana.
Watch out: Choose separately for each symbol. A {W/U} card is both white and blue even if you use only one color to cast it.
After you cast a spell, this creature grows if the mana you spent is greater than its power or its toughness.
This permanent cannot be destroyed by lethal damage or an effect that says “destroy.”
Watch out: It can still be exiled or sacrificed. A creature with toughness 0 or less still goes to the graveyard.
Infusion checks whether you gained life earlier in the current turn. The amount and your net life change do not matter.
Create a Clue artifact token. You may later pay two mana and sacrifice that Clue to draw a card. Investigating itself does not draw the card.
As you cast the spell, you may pay its extra kicker cost. The card tells you what changes if you do.
Watch out: You decide and pay while casting. You do not get to add kicker after the spell has resolved.
This label groups abilities that reward a land entering under your control. The rest of each card tells you its effect.
Watch out: A land entering from a spell can trigger landfall too. The label itself adds no rules; read the actual ability.
When this source deals damage, its controller gains that much life at the same time.
Watch out: This also works for noncombat damage. It uses the damage actually dealt, not simply the creature’s printed power.
A planeswalker’s loyalty is the number of loyalty counters on it. Its loyalty costs add or remove counters, and damage removes that much loyalty.
Watch out: A planeswalker with 0 loyalty goes to the graveyard. Adding more counters does not let you activate it a second time in the same turn.
Magecraft abilities trigger when you cast or copy an instant or sorcery. Each card describes its own reward. A copy can trigger magecraft even when that copy was not cast.
This attacking creature cannot be blocked by just one creature; at least two blockers are needed.
Watch out: It can still go unblocked. Losing one blocker after blocks are declared does not undo the original block.
Put the stated number of cards from the top of the named player’s library into that player’s graveyard.
Watch out: Milling is not drawing. An empty library makes you lose when you must draw from it, not merely when its last card is milled.
You may cast this card face down as a nameless 2/2 creature for three mana. With priority, pay its morph cost to turn it face up as a special action. This is not casting it again and does not use the stack.
Casting an instant or sorcery triggers opus. Spending at least five mana to cast that spell upgrades the result.
Pay the overload alternative cost to replace the word target with each in the spell’s text. An overloaded spell does not target, so it can affect creatures with hexproof if its other conditions permit.
The first resolved paradigm spell of a name is exiled and lets you cast a free copy at the beginning of each of your future first main phases.
The set’s Pest tokens gain life when they attack. Fractals begin as 0/0 creatures and rely on the counters supplied by their creating effect.
A prepared creature gives you a copy of its inset spell in exile. Cast the copy, pay its cost, and the creature becomes unprepared.
When its instruction makes a creature prepared, it gives you access to a copy of its separate prepare spell. You may cast that copy while the permanent remains prepared and on the battlefield.
Watch out: Pay the copy’s costs and obey instant or sorcery timing. Casting it unprepares the permanent; the creature itself remains. You cannot cast the prepare spell straight from your hand.
This creature may block creatures with flying.
Watch out: Reach does not give it flying or make its own attacks harder to block.
These abilities reward casting an instant or sorcery that targets a creature. Each card supplies its own reward.
A Role is an Aura token with the ability written on the creating card. If you control several Roles attached to the same permanent, keep only your newest one. Monster grants +1/+1 and trample; Royal grants +1/+1 and ward one.
Move a permanent you control from the battlefield to its owner’s graveyard.
Watch out: Sacrifice is not destruction: indestructible does not stop it. You cannot sacrifice a teammate’s permanent unless an effect specifically permits it.
Look at the stated number of cards from the top of your library. Put any number on the bottom and the rest back on top, choosing their order.
Watch out: Scry does not draw a card. Cards you move to the bottom do not go to the graveyard.
Repeated useful cards arriving late may indicate an open color; one card is weak evidence.
While this spell is on the stack, players cannot cast other spells or activate abilities that are not mana abilities.
Watch out: Triggered abilities still trigger, and mana abilities and special actions are still allowed. Split second does not mean “cannot be countered.”
Choose one or more modes and add their listed costs to the spell’s base cost. A free-cast effect does not waive spree’s additional costs. You still must choose at least one mode.
When you cast this spell, copy it for every other spell already cast this turn by any player. You may choose new targets for the copies. Countering the original spell does not remove its separate storm trigger.
If a permanent with a stun counter would untap, remove one stun counter instead and leave it tapped.
Watch out: The counter does not tap an untapped permanent by itself. Several stun counters can stop several separate untaps.
Look at the stated number of cards from the top of your library. Put any number into your graveyard and the rest back on top in your chosen order.
Watch out: Surveil does not draw a card. Unlike scry, unwanted cards go to the graveyard instead of the bottom.
Instead of casting from hand, pay the suspend cost and exile the card with the stated time counters. Remove one at each of your upkeeps. When the last is removed, you may play it for free; a creature cast this way gains haste.
Cards helping each other do a useful job.
Tap means turn a permanent sideways; untap means return it upright. A tap symbol in a cost means you must tap that permanent to pay.
Watch out: Being tapped by another effect does not activate an ability or produce mana. Creatures normally cannot pay their own tap-symbol costs until you have controlled them since your turn began.
An attacking creature can assign excess combat damage to what it is attacking after assigning lethal damage to every blocker.
Watch out: It does not automatically send all damage past a small blocker. Trample on a blocking creature does not send damage to the attacking player.
A standard Treasure token is an artifact you can tap and sacrifice to add one mana of any color.
Watch out: A Treasure is not a land. Using it spends the token; it does not remain for another turn.
Attacking does not tap this creature.
Watch out: It must still be untapped to be declared as an attacker. Vigilance does not remove summoning sickness.
When an opponent’s spell or ability targets this permanent, ward triggers. That spell or ability is countered unless the opponent pays the ward cost.
Watch out: Ward is not hexproof: the opponent can target it and choose whether to pay. An effect that does not target does not trigger ward.
