Reveillark + Body Double + Goblin Bombardment

Reveillark

Body Double

Goblin Bombardment

How it works

1. Activate Goblin Bombardment by sacrificing Body Double.
2. When Body Double leaves the battlefield, it triggers its Reveillark ability, returning itself from your graveyard to the battlefield as a copy of Reveillark.
3. Resolve the Goblin Bombardment ability.
4. Repeat.

This lethal loop relies on Body Double entering the battlefield as a copy of Reveillark from your graveyard, allowing it to inherit that legendary elemental's trigger when it leaves the battlefield. By using Goblin Bombardment to sacrifice Body Double, you immediately trigger its copied ability to return itself right back from the graveyard, ready to copy Reveillark once again. Because Reveillark's leave-the-battlefield ability brings back creatures with power 2 or less, Body Double fits the criteria perfectly while fueling Goblin Bombardment with endless sacrifices to deal infinite damage to any target.
