How it works
Activate Marina by tapping it, unlocking Awakening Hall.
Awakening Hall triggers, returning all creature cards in your graveyard to the battlefield.
Activate Phantom Train by sacrificing one of the returned creatures.
When the creature dies, Marina triggers, and Funeral Room triggers if it's unlocked.
Resolve the Marina trigger, untapping it.
Resolve the Funeral Room trigger, if applicable, causing each opponent to lose 1 life and you to gain 1 life.
Resolve the Phantom Train ability.
Activate Marina by tapping it, locking Awakening Hall.
Repeat steps 3 through 7 once.
Repeat from step 1.
This intricate loop relies on Marina Vendrell toggling the doors of your Rooms to repeatedly harvest and sacrifice your entire graveyard. When Marina unlocks the Awakening Hall half of Funeral Room // Awakening Hall, every creature card floods back from your graveyard to the battlefield, setting up the fodder you need. You can then use Phantom Train to sacrifice one of those newly returned creatures, which triggers the drain effect from the Funeral Room side of the split card. To make this engine self-sustaining, Thornbite Staff equips itself to Marina (who is a Shaman) and uses its untap ability triggered by creature deaths to let you tap Marina over and over again to lock and unlock the doors, fueling an endless cycle of sacrifice, drains, and resurrections.
