Twincast + Reverberate

Twincast

Reverberate

How it works

1. Cast any instant or sorcery spell, or wait for an opponent to cast one.
2. Holding priority, cast Reverberate by paying , targeting that spell.
3. Cast Twincast by paying , copying Reverberate, with the copy targeting Reverberate.
4. Resolve the copy of Reverberate, copying the original Reverberate, with the copy targeting the original Reverberate.
5. Repeat step 4.

This clever little loop starts when you cast any instant or sorcery, which immediately puts a spell onto the stack for Reverberate to copy. You then unleash Twincast to duplicate your initial Reverberate, setting up a self-sustaining echo chamber where a copied Reverberate targets the original, which in turn generates another copy of itself. Because this mirroring process can repeat indefinitely without ever consuming a new card, it fuels infinite magecraft triggers to win the game on the spot.
