Swarm Intelligence + Narset's Reversal + Frantic Search

Swarm Intelligence

Narset's Reversal

Frantic Search

How it works

1. Cast Frantic Search by paying 2.
2. Swarm Intelligence triggers, creating a copy of Frantic Search.
3. Resolve the copy of Frantic Search, looting twice and untapping three lands you control that can tap to produce at least 1.
4. Activate the three lands by tapping them, adding at least 1.
5. Holding priority, cast Narset's Reversal by paying , targeting Frantic Search.
6. Swarm Intelligence triggers, creating a copy of Narset's Reversal, targeting the original Narset's Reversal.
7. Resolve the Narset's Reversal copy, creating a copy of the original Narset's Reversal targeting Frantic Search and returning the original Narset's Reversal to your hand.
8. Resolve Narset's Reversal, creating a copy of Frantic Search and returning it to your hand.
9. Resolve Frantic Search, looting twice and untapping three lands you control that can tap to produce at least 1.
10. Activate the three lands by tapping them, adding at least 1.
11. Repeat.

This wondrous loop is anchored by Swarm Intelligence, whose passive enchantment ability turns every spell you cast into a twin. By casting Frantic Search, you draw and discard while untapping your lands to pay for your spells, setting up the engine. You then weave Narset's Reversal into the stack to continually copy and bounce your spells back to your hand rather than letting them resolve normally. Through this recursive dance, Swarm Intelligence and Narset's Reversal feed off each other to endlessly recast Frantic Search, generating boundless resources for your victory.
