Unholy Annex: The three-mana black door draws at your end step, then drains if you control a Demon or costs you life otherwise. Track your life total and access to a Demon rather than assuming the draw is free. Ritual Chamber: The five-mana black door makes a 6/6 flying Demon when unlocked. It can be cast first for a substantial threat, or later to switch Unholy Annex's life loss into a drain.

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.
