How it wins

Produce Mutagen through Mutants and other creatures, then convert artifact entries and counters into a large evasive or trampling attack.

Early
Develop an early creature and the colored mana your hand needs.
Middle
With Genghis and Donatello present, a Mutant that makes Mutagen can create several artifact-entry counters before you spend any tokens.
Finish
Produce Mutagen through Mutants and other creatures, then convert artifact entries and counters into a large evasive or trampling attack.

What it needs

Commit when repeated useful cards and enough support make a complete deck in these colors.

Four checks while you draft

  1. 1
    A functional opening

    Can I affect the board before the payoff?

    A defensive body plus a Mutagen supports artifacts and counters. Spend the Mutagen in a main phase when its counter matters.

  2. 2
    The cards that make it work

    Do my actual cards enable this plan?

    With Genghis and Donatello present, a Mutant that makes Mutagen can create several artifact-entry counters before you spend any tokens.

  3. 3
    Interaction and a finish

    Can I stop their strongest play and finish a stalled game?

    Produce Mutagen through Mutants and other creatures, then convert artifact entries and counters into a large evasive or trampling attack.

Choose the missing job before another reward that needs it.

What to take next

The key card is present but its support is thin.

Prioritize useful support such as Crustacean Commando or Slithering Cryptid.

With Genghis and Donatello present, a Mutant that makes Mutagen can create several artifact-entry counters before you spend any tokens.

Your deck already enables the plan but is losing the early turns.

Take a castable early creature or efficient answer before a second expensive payoff.

Mutagen activation is sorcery speed. Make the creature large enough before combat rather than planning to surprise a blocker.

The support is missing

Favor independently useful creatures and interaction if the narrow support does not arrive.

Signals to watch
  • More than one late card such as Crustacean Commando or Slithering Cryptid is stronger evidence than one gold card.

Repeated useful cards are clues, not proof that the colors are open.

Don’t
Avoid the setup mistake

Mutagen activation is sorcery speed. Make the creature large enough before combat rather than planning to surprise a blocker.

Playing against this plan

Use removal in response to a Mutagen ability to waste the upgrade and target. Do not wait until a flyer is outside your removal’s range.

Adapt the plan to your format

One-pickSealed
With one pick, fill the missing early play, answer or support card before adding another narrow payoff. The plan must work without drawing its key card.Compare complete builds from the cards you opened. Keep the castable curve and interaction even if the draft theme is only partly supported.
