  Artifact Creature — Treasure DogR

  Sacrifice-recursion with a catch: one card can return the other from the graveyard, but the return ability has an extra cost (sacrificing another creature, discarding a card, or tapping with no way to untap) the pair can't pay by itself. It works once — something else must keep supplying the fodder to make it repeatable.

• Phyrexian Dreadnought

  Artifact Creature — Phyrexian DreadnoughtC
