Errant, Street Artist + Reality Spasm + Fury Storm

Errant, Street Artist

Reality Spasm

Fury Storm

How it works

1. Cast Reality Spasm by paying at least 3, targeting at least three permanents and choosing the untap mode.
2. Holding priority, cast Fury Storm by paying its mana cost, 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 clever loop turns Errant, Street Artist into a relentless copying engine, using Reality Spasm to constantly untap both Errant and the mana-producing permanents required to pay for its ability. Because Reality Spasm can target any permanents, you fuel the entire sequence while generating infinite mana from those tapped lands or rocks. Meanwhile, Fury Storm kicks off the chaos and can benefit from your commander's tax if cast from the command zone, creating an infinite storm of spells and magecraft triggers.
