• Illicit Masquerade

  3B

  EnchantmentB

  Graveyard pair: one card brings creatures back from the graveyard repeatedly (or a creature that returns itself), and the other keeps feeding the loop — a recurring reanimator with a payoff, or a sacrifice outlet with a self-recurring creature.
• Chandra, Flameshaper

  5RR

  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.
• Xho Cai, Flickering Talon

  URW

  Legendary Creature — Bird MonkRUW

  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.

• Skycoach Conductor // All Aboard

  2UU

  Creature — Bird Pilot // InstantU

  Blink loop: one card blinks creatures and the other's enter-the-battlefield effect fires on every re-entry — and the blink repeats without limit: it costs nothing, the partner's own entry pays for it (Deadeye Navigator + Peregrine Drake), or the partner returns the blink spell to your hand.
• Mirrorhall Mimic // Ghastly Mimicry

  3U

  Creature — Spirit // Enchantment — AuraU

  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.).
• Slimefoot and Squee

  BRG

  Legendary Creature — Fungus GoblinBGR

  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. Real, repeatable value — not an infinite loop on its own.
