Glen Elendra Pranksters + Phyrexian Walker + Teferi, Mage of Zhalfir + Rograkh, Son of Rohgahh

Glen Elendra Pranksters

Phyrexian Walker

Teferi, Mage of Zhalfir

Rograkh, Son of Rohgahh

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.

By leveraging Teferi, Mage of Zhalfir to give your entire hand flash during an opponent's turn, you open the door to casting your zero-mana artifacts and creatures at instant speed. When you drop Phyrexian Walker or Rograkh, Son of Rohgahh, Glen Elendra Pranksters sees the spell cast and triggers to bounce whichever zero-cost creature is currently sitting on the battlefield right back to your hand. Because these creatures cost nothing to play, you can continuously loop them back and forth indefinitely. This elegant little engine generates infinite enters-the-battlefield and leaves-the-battlefield triggers along with an arbitrarily high storm count, all protected behind Teferi's strict lockdown on your opponents' timing.
