  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.

  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.).
