How it works
Cast Burnt Offering by paying and sacrificing a creature with mana value 3 or greater.
Extus triggers, targeting any applicable creature card in your graveyard.
Holding priority, cast Dualcaster Mage by paying 1.
When Dualcaster Mage enters the battlefield, it triggers.
Holding priority, activate Goblin Bombardment by sacrificing Dualcaster Mage, dealing 1 damage to any target.
Resolve the Dualcaster Mage trigger, copying Burnt Offering.
Extus triggers, returning Dualcaster Mage to your hand from your graveyard.
Resolve the Burnt Offering copy, adding at least B/R.
Repeat from step 3.
If the sacrificed creature had mana value 4 or greater, this combo nets infinite black and red mana.
This intricate loop relies on constantly recycling Dualcaster Mage to continuously copy and recast Burnt Offering, using the mana generated to fund the cycle while Goblin Bombardment provides the necessary sacrifice outlet. Each time Burnt Offering is cast or copied, Extus, Oriq Overlord's magecraft ability triggers to conveniently return Dualcaster Mage right back to your hand from the graveyard. Because Burnt Offering sacrifices a creature to yield mana proportional to its value, you can cleanly generate an infinite surplus of black and red mana, infinite death triggers, and infinite damage to close out the game.
