Glen Elendra Pranksters + Crimson Kobolds + Rograkh, Son of Rohgahh + Quicksilver, Speedster

Glen Elendra Pranksters

Crimson Kobolds

Rograkh, Son of Rohgahh

Quicksilver, Speedster

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 loop turns free casting costs into a relentless engine during your opponent's turn, anchored by Quicksilver, Speedster to ensure you can cast whenever you need. With Quicksilver, Speedster providing the timing, you can repeatedly deploy Crimson Kobolds and Rograkh, Son of Rohgahh for zero mana. Each time you cast one of these free spells, Glen Elendra Pranksters triggers to bounce the other free creature right back to your hand, resetting the loop for infinite enters-the-battlefield triggers, leaves-the-battlefield triggers, and storm count.
