Glen Elendra Pranksters + Crimson Kobolds + Shield Sphere + Sally Sparrow

Glen Elendra Pranksters

Crimson Kobolds

Shield Sphere

Sally Sparrow

How it works

1. During an opponent's turn, cast the 0-cost creature in your hand by paying 0.
2. Glen Elendra Pranksters triggers, returning the other 0-cost creature from the battlefield to your hand.
3. Resolve the spell from step 1.
4. Repeat.

This clever loop hinges entirely on Sally Sparrow's ability to let you cast creature spells at instant speed during an opponent's turn, turning zero-mana investments into recurring instant-speed triggers. By alternating between playing Crimson Kobolds and Shield Sphere—which cost nothing to cast—you can feed them directly into Glen Elendra Pranksters's triggered ability to continuously bounce the other back to your hand. As these creatures repeatedly enter and leave the battlefield, Sally Sparrow's once-per-turn-limited investigation sits alongside an endless storm count and continuous entry triggers.
