Combat Celebrant + Displacer Kitten + Spellbinder + Temur Ascendancy

Combat Celebrant

Displacer Kitten

Spellbinder

Temur Ascendancy

How it works

1. Declare Combat Celebrant and the creature with Spellbinder attached as attackers, choosing to exert Combat Celebrant as it attacks.
2. Combat Celebrant triggers, causing you to untap all other creatures you control and to get an additional combat phase after this one.
3. Deal combat damage using the creature that has Spellbinder attached.
4. Spellbinder triggers, causing you to copy a card exiled with it, and cast the copy without paying its mana cost.
5. Displacer Kitten triggers, blinking Combat Celebrant.
6. Resolve the spell cast in step 4.
7. Repeat each combat phase.

This intricate loop leverages Combat Celebrant's exert ability to chain infinite combat phases, while Temur Ascendancy grants your army haste and fuels your hand with extra cards whenever massive threats hit the board. As your creatures swing, the creature equipped with Spellbinder deals combat damage to trigger a free copy of an imprinted instant spell. Casting that noncreature spell triggers Displacer Kitten, which blinks Combat Celebrant out of play and right back onto the battlefield—clearing its exert restriction entirely so you can do it all over again in the next combat step.
