Goblin Bombardment + Dualcaster Mage + Second Sunrise

Goblin Bombardment

Dualcaster Mage

Second Sunrise

How it works

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

This ingenious loop harnesses the recursive power of Second Sunrise to pull off a fiery, game-ending sequence. By casting Second Sunrise and responding with Dualcaster Mage, the Mage's enters-the-battlefield ability immediately targets the original sorcery on the stack. Before that copy resolves, you use Goblin Bombardment to sacrifice the Dualcaster Mage for damage, sending it straight to the graveyard. When the copied Second Sunrise resolves, it brings Dualcaster Mage right back to the battlefield to copy the spell anew, letting you repeat this sacrifice-and-return cycle indefinitely to incinerate any target.
