• Kozilek's Unsealing

  2U

  EnchantmentU

  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.
• Intruder Alarm

  2U

  EnchantmentU

  One-directional refresh: one card can untap permanents the other wants to reuse. Not self-sustaining on its own — the untapper has to keep showing up.
