Roaring Furnace: The two-mana red door deals damage to an opposing creature equal to cards in your hand when its trigger resolves. Casting it reduces your hand first; do not count the Room card still in hand for damage. Steaming Sauna: The five-mana blue door draws a card at each of your end steps and removes your maximum hand size. It provides no damage trigger unless you separately have red mana and unlock Roaring Furnace.

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.
