Goblin Bombardment + Dualcaster Mage + Ascend from Avernus

Goblin Bombardment

Dualcaster Mage

Ascend from Avernus

How it works

1. Cast Ascend from Avernus by paying 3
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Ascend from Avernus.
4. Holding priority, activate Goblin Bombardment by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Ascend from Avernus
6. Resolve the Ascend from Avernus copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This dazzling loop begins by casting Ascend from Avernus, laying the groundwork for a massive graveyard-to-field recursion. Before it resolves, you drop Dualcaster Mage into the mix, whose triggered ability targets the spell on the stack to copy it. By immediately using Goblin Bombardment to sacrifice that very same Dualcaster Mage, you ensure it is sitting safely in your graveyard just in time for the copied Ascend from Avernus to pull it right back onto the battlefield. This freshly returned Dualcaster Mage triggers all over again to copy the original spell, creating a self-sustaining loop that repeatedly cycles your mage through the graveyard while the Bombardment converts each iteration into an endless storm of damage.
