Dáin, Lord of the Iron Hills

Dáin plus two qualifying permanents creates a potent attack tax, but a removable 2/2 is most likely a metagame-dependent anti-aggro card.

Could be wrong if Revealed artifact and legendary density may make the condition much more routine, or removal may make investing in Dáin untenable.

It can tax wide attacks after modest setup, but Fatal Push and efficient low curves leave this conditional 2/2 as a narrow testing candidate.

Could be wrong if Cheap artifact/legend shells could establish the story early enough to make its combat tax a real sideboard staple.

Artifact decks can enable Dáin cheaply, but it is a removable 2/2 and only matters versus combat, a low-impact baseline for Modern.

Could be wrong if A competitive artifact shell may reliably activate it immediately and value the tax against Boros Aggro or other creature decks.

Fast artifacts can enable an early tax, but Dáin is fragile, vulnerable as a legend, and irrelevant against much of Legacy's combo-centric field.

Could be wrong if Artifact prison strategies could exploit fast mana and a favorable creature metagame better than expected.

Dáin counts itself, so matching decks often get a two-mana multiplayer Ghostly Prison; creature fragility keeps it below established enchantment taxes.

Could be wrong if Optimized lists may prefer more resilient prison pieces, or artifact/legend density may make this unusually efficient.

A vigilant two-drop is useful early, and Dáin plus two artifacts, legends, or Sagas makes attacking into it substantially harder.

Could be wrong if Unknown artifact, legend, and Saga density may make Storied either routine or too inconsistent for a premium rating.
