Intruding Soulrager

The activation reads as a burn spell, but it plays like an aristocrats outlet dressed in Izzet colors. Sacrificing a Room as the tap cost is the wrinkle: an unlocked Room has already handed you its front-half effect, so this Spirit harvests a permanent you have finished with and converts it into two damage to each opponent plus a card. That reframes the Room from spent fixture to stored fuel, cashed without spending anything from hand. The damage is capped and repeatable rather than front-loaded, and the card draw keeps the fuel line replenished, which is why it grinds rather than bursts. Vigilance resolves the one scheduling conflict the design would otherwise create: attacking normally taps a creature, so a body wanting to both swing and hold up an ability would be stuck picking one. Here the Spirit can attack and stay untapped to fire the ability on the same turn, applying pressure and payoff together. The tap cost is paid by the activation itself, not by combat, so the only real limiter is supply. The engine turns only inside a shell built to churn out Rooms it no longer needs, which is a specific ask; without that pipeline it is a 2/2 with vigilance and a dead ability. Where the Rooms flow, it is a slow, repeating drain that peels two life and one card off the top every turn a fuel source is available.
