Charred Foyer // Warped Space

The Room mechanic splits a permanent into two doors you can unlock independently, and this one turns that structure into a two-stage impulse-draw engine. The first door, Charred Foyer, gives you a card off the top every upkeep with permission to play it that turn: a slow, grinding advantage that reads like a red version of the exile-and-play package that mono-red midrange has leaned on for years. The second door, Warped Space, is where the design gets interesting, because it lets you cast one exiled spell for free each turn. Stack the two and the upkeep exile stops being a fair card-per-turn trickle and becomes a way to deploy your best draw at no mana cost, freeing the rest of your turn entirely. The tension the Room framing resolves is sequencing: you are never forced to pay for both halves at once, so you can land Charred Foyer early as a value clock and unlock Warped Space later once you have the mana and a board to protect it. The clause is scoped tightly enough to keep it honest, though: once each turn, and only for spells cast from exile, so it rewards decks already generating exile-play effects rather than functioning as universal free-spell acceleration. It is a card built for the patient red deck, the one willing to spend a turn arming an engine before it starts firing.
