Karmic Guide + Reveillark + Goblin Bombardment

Karmic Guide

Reveillark

Goblin Bombardment

How it works

1. Activate Goblin Bombardment by sacrificing Karmic Guide.
2. Activate Goblin Bombardment by sacrificing Reveillark.
3. When Reveillark dies, it triggers, returning Karmic Guide and up to one other creature with power 2 or less from your graveyard to the battlefield.
4. When Karmic Guide enters the battlefield, it triggers, returning Reveillark from your graveyard to the battlefield.
5. Resolve the Goblin Bombardment ability from step 2.
6. Repeat.

This classic engine creates an endless loop of sacrifice and resurrection by letting Karmic Guide and Reveillark endlessly fish each other out of the graveyard. When you sacrifice Reveillark to Goblin Bombardment, its leaves-the-battlefield trigger brings back Karmic Guide alongside another small creature, and the returning Karmic Guide's entry trigger immediately plucks Reveillark right back out of the graveyard. Goblin Bombardment converts this perpetual motion machine into infinite damage for your opponents, cleanly closing out the game using nothing more than a mutually supportive pair of winged resurrection specialists and a sacrifice outlet.
