Errant, Street Artist + Reality Spasm + Swarm Intelligence

Errant, Street Artist

Reality Spasm

Swarm Intelligence

How it works

1. Cast Reality Spasm by paying at least 3, targeting at least three permanents and choosing the untap mode.
2. Swarm Intelligence triggers, copying Reality Spasm, targeting at least three permanents.
3. Holding priority, activate at least two mana-producing permanents you control by tapping them, adding at least 1.
4. Activate Errant by paying 1 and tapping it, copying the Reality Spasm copy, targeting Errant and at least two mana-producing permanents you control.
5. Resolve the copy of Reality Spasm from step 3, untapping Errant and at least two mana-producing permanents you control.
6. Repeat from step 3.

This fascinating loop relies on the constant, self-sustaining recursion of Reality Spasm fueled by the permanents it leaves in its wake. When you cast Reality Spasm, Swarm Intelligence automatically seeds the stack with an initial copy, giving you two spells to work with right off the bat. From there, Errant, Street Artist steps in as the engine's core mechanic, using its active tap ability to duplicate the copies over and over while untapping itself in the process. As long as your targeted lands and mana rocks yield enough juice to cover Errant, Street Artist's activation cost, you can endlessly loop the untap mode to generate infinite mana and trigger any magecraft effects you have waiting in the wings.
