Curse of Trap's Hold

Enchant Player

At the beginning of enchanted player's first main phase, that player puts a rot counter on target artifact, planeswalker, or land they control. Then, they attach Curse of Trap's Hold to target player.

Permanents with rot counters on them are 2/2 colorless rot creatures in addition to their other types, and lose all other abilities.

Nothing ever leaves the trap house. They simply evolve.
