Errant, Street Artist + Reality Spasm + Refuse // Cooperate

Errant, Street Artist

Reality Spasm

Refuse // Cooperate

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 Cooperate from your graveyard 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 delightful loop turns a single casting of Reality Spasm into an endless mechanical engine by leveraging the graveyard half of Refuse // Cooperate to copy the spell and kickstart the chain. Once the copy is on the stack, Errant, Street Artist steps in to replicate it repeatedly for a modest mana investment, untapping itself and your mana sources with every iteration to generate infinite mana. Because the copied spells are continually generated without being cast from hand, Errant, Street Artist meets its own restriction effortlessly, fueling infinite triggers for any your spell-copying needs.
