  B/GB/G

  Creature — Elf ShamanBG

  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.

  Legendary Planeswalker — ChandraR

  Copy engine: one card makes copies of a creature — once a turn, or once for each time you pay its cost — and each copy pays off: the creature's enter-the-battlefield effect fires again, or the hasty copy uses its tap ability. Real, repeatable value — every copy has its turn or its price, so it never goes infinite on its own.
