Goblin Bombardment + Dualcaster Mage + Extract from Darkness

Goblin Bombardment

Dualcaster Mage

Extract from Darkness

How it works

1. Cast Extract from Darkness by paying its mana cost
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Extract from Darkness.
4. Holding priority, activate Goblin Bombardment by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Extract from Darkness
6. Resolve the Extract from Darkness copy, causing each player to mill two cards and returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This elegant loop sets up a self-sustaining cycle of recursion, damage, and disruption by leveraging Dualcaster Mage to continuously copy Extract from Darkness. Each time Dualcaster Mage enters the battlefield, its triggered ability targets the original sorcery on the stack, allowing you to sacrifice it to Goblin Bombardment in response and send it safely to the graveyard. The resulting copy of Extract from Darkness then resolves, milling your opponents while returning Dualcaster Mage straight back to the battlefield to repeat the entire process. Goblin Bombardment acts as the ultimate pressure valve here, translating this endless loop of leaves-the-battlefield and death triggers into infinite damage to close out the game.
