Play early Mice and use efficient targeting effects to trigger valiant while pushing combat damage. Gnaw targets Hero first, triggering its counter before its damage is measured as Gnaw resolves.

How this changes your picks

Rules-derived
Take it when
Play early Mice and use efficient targeting effects to trigger valiant while pushing combat damage. Look for support such as Heartfire Hero and Flowerfoot Swordmaster.
What to take next
Gnaw targets Hero first, triggering its counter before its damage is measured as Gnaw resolves.
Wrong pick
Valiant happens only once per creature per turn. Loading several tricks into one combat risks losing them to removal.
Mana & splash
Count the colored sources needed to cast this card on time; a synergy payoff is not a reason to weaken an otherwise consistent mana base.

How to read this

Observational, not a causal bonus. Both cards must be in the deck. Drawn means opening hand or normally drawn; each card counts once per game. Game-level approximate intervals do not account for repeated games by the same drafter.

At least 100 games in each of four drawn/not-drawn groups; adjusted for game length and screened by the lower confidence bound. Do not add these points to a card’s win rate.
