Ashnod's Altar

How it works

1. Activate Marina by tapping it, unlocked Spiked Corridor.
2. Spiked Corridor triggers, creating three 1/1 Devil creature tokens.
3. Activate Ashnod's Altar by sacrificing a Devil, adding CC.
4. When the Devil dies, it and Marina trigger.
5. Resolve the Devil's trigger, dealing 1 damage to any target.
6. Resolve the Marina trigger, untapping it.
7. Activate Marina by tapping it, locking Spiked Corridor.
8. Repeat steps 3 through 6 one additional time.
9. Repeat from step 1.

This intricate loop turns the versatile utility of Marina Vendrell into a devastating damage engine by leveraging the room-locking mechanic to repeatedly cycle through Spiked Corridor // Torture Pit's door states. When Marina taps to unlock the Spiked Corridor side, it populates your board with three 1/1 red Devil creature tokens, which you can immediately feed to Ashnod's Altar to generate a steady stream of colorless mana. As those Devils perish, their dying triggers ping your opponents while Thornbite Staff—conveniently attached thanks to Marina's Shaman creature type—pries Marina back open with its untap trigger. By continuously locking and unlocking the room with Marina Vendrell's tap ability, you harvest infinite sacrifices, death triggers, and damage amplified directly by the room's own replacement effect.
