Ghostly Dancers

Eerie's cleverest move is folding two very different clocks into one reward. The ability treats an enchantment you control resolving onto the battlefield and a door finishing its unlock sequence as equivalent triggers for the same 3/1 flying Spirit engine. That equivalence is what the whole design leans on: a deck built around this creature is always advancing one of those two clocks, and either one spits out an evasive body. The entry trigger tightens the loop by feeding the same axes it rewards, either buying back an enchantment you have already spent for value or unlocking a Room door directly, so the flier can chain into its own Eerie payoff the turn it arrives. What keeps the engine from spiraling is that the entry ability is strictly one-shot, and the tokens, though evasive, are 3/1s that fold to almost any point of damage or a stiff blocker. Sustained token production therefore demands genuine enchantment and Room density behind the card rather than a single lucky trigger. It reads as a payoff only once the shell around it commits to enchantments and Rooms as a renewable resource, which is exactly the build-around discipline a Spirit-flavored value engine should ask for.
