So go fill your graveyards with Surveil, bring stuff back from those graveyards, and go to town
You can play the entire Dark Depths combo from your graveyard each turn, play two fetch lands (or the same fetch twice) for four total landfall triggers, make your opponents cry with Strip Mine this card is absurdly powercrept
But my intuition for creatures comes in the form of those that come back from the graveyard, like Adorned Pouncer, Boneyard Scourge, or Multani, Yavimayas Avatar
Stuffy Doll sees competitive metagame play in 1 format(s): Commander
For example, challenges to a character with Resist+2 are reduced by two points before damage is assigned - this makes them beefy challengers in their own right or valuable questers who can withstand blows from your opponents before being banished
For the same amount of mana they now get a commander that rewards the decks go-wide artifact strategy and its unearth subtheme, at a terrifyingly efficient rate
