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 Flowerfoot Swordmaster and Intrepid Rabbit.
- 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.

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.
