Glen Elendra Pranksters + Shield Sphere + Kobolds of Kher Keep + Vernal Equinox

Glen Elendra Pranksters

Shield Sphere

Kobolds of Kher Keep

Vernal Equinox

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 little loop turns free, zero-mana creatures into an endless cycle of entering and leaving the battlefield right under your opponents' noses. Vernal Equinox provides the crucial static engine that lets you cast creatures at instant speed, opening up the window to play them during an opponent's turn. Once you do, Glen Elendra Pranksters triggers to bounce your other free threat—whether that's a lowly Kobolds of Kher Keep or a sturdy Shield Sphere—right back to your hand so you can recast it again and again. Shield Sphere is particularly resilient to any collateral damage thanks to its toughness, though any zero-drop will do to keep the chain indefinitely fueled.
