  One-shot copy enabler: a card enters as a copy of another (Phantasmal Image, Body Double, Phyrexian Metamorph), firing the partner's substantive ETB once. Not a repeating chain — fires once on entry — but valuable when the partner's ETB is combo-grade (graveyard reanimator, mana doubler, etc.).

  2BGU

  Legendary Creature — Nightmare Beast ElementalBGU

  Recursion engine: one card can reanimate repeatedly (an activated ability, or a return that comes back once a turn), and the other is a creature worth bringing back again and again — or a creature you recast from your graveyard beside a sacrifice outlet that doesn't pay for the recast. Real, repeatable value — not an infinite loop on its own.
