Glen Elendra Pranksters + Crimson Kobolds + Phyrexian Walker + Teferi, Mage of Zhalfir

Glen Elendra Pranksters

Crimson Kobolds

Phyrexian Walker

Teferi, Mage of Zhalfir

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 elegant loop turns zero-mana creatures into a flurry of triggers by leveraging the flash granted to your hand by Teferi, Mage of Zhalfir during an opponent's turn. With Teferi also locking down opponent timing, you cast Crimson Kobolds or Phyrexian Walker for free, triggering Glen Elendra Pranksters to bounce the other zero-mana creature back to your hand. By endlessly alternating between casting one and bouncing the other, you generate infinite creature enters-the-battlefield and leaves-the-battlefield triggers along with an astronomical storm count.
