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.
