Dollhouse of Horrors

Dollhouse of Horrors is a Commander card at heart — the slow, incremental value it generates is exactly what a 100-card singleton format rewards, and creature-heavy graveyard strategies have the density to keep it firing every turn. In Modern and Legacy, the five-mana artifact investment is too slow and too easy to interact with at instant speed, and dedicated reanimation or recursion packages do the job more efficiently. Pioneer gives it a slightly more forgiving field, but the same fundamental problem applies — it asks too much mana over too many turns when faster threats dominate. Stick to Commander, where the inevitability it creates becomes a genuine closing engine.
