Underwater Tunnel / Slimy Aquarium
Enchantment — Room
(You may cast either half of this spell, unlocking the door to that room when it enters. This card has the abilities, colour and mana cost of that room. As a sorcery, you may pay the mana cost of a locked door to unlock it. The abilities, colour and mana cost of that door are added to this permanent. If this enchantment enters without being cast, both rooms will be locked. Copying this enchantment also copies the locked status of the rooms.)
Underwater Tunnel
When you unlock this door, surveil 2. (Look at the top two cards of your library, then put any number of them into your graveyard and the rest back on top of your library in any order.)
Slimy Aquarium
When you unlock this door, manifest dread, then put a +1/+1 counter on that creature. (Look at the top two cards of your library. Put one onto the battlefield face down as a 2/2 creature and the other into your graveyard. Turn it face up at any time for its mana cost if it's a creature card.)
