Underwater Tunnel // Slimy Aquarium

Description

Underwater Tunnel // Slimy Aquarium (DSK-79) is a Room enchantment from Duskmourn: House of Horror that has two door faces you may cast individually. The front door, Underwater Tunnel, unlocks to surveil 2, letting you put cards into your graveyard or reorder your library. The back door, Slimy Aquarium, unlocks to manifest dread and then put a +1/+1 counter on the manifested creature, creating a 2/2 face-down creature and potentially enabling turn-face-up interactions.
