Errant, Street Artist + Reality Spasm + Flare of Duplication

Errant, Street Artist

Reality Spasm

Flare of Duplication

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 Flare of Duplication by paying its mana cost or by sacrificing a red nontoken creature, 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 Reality Spasm into an infinite mana engine by exploiting how copy targets can select the original caster and their own fueling pieces. When you cast Reality Spasm and copy it with Flare of Duplication, you lay the groundwork for Errant, Street Artist to continuously replicate the copied spell. Because Errant, Street Artist can specifically target itself and your mana-producing permanents with the untap mode, every resolution safely resets your board state and leaves you ready to repeat the process indefinitely.
