  Legendary Creature — Human Rebel WarlockW

  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.

  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.
• The Mighty Thor, Jane Foster

  Blink engine: one card blinks creatures — once a turn, once a combat, or each time you pay — and the other's enter-the-battlefield effect fires again on every blink. Real, repeatable value — never infinite on its own.
