Dualcaster Mage + Sevinne's Reclamation + Hammerhead, Maggia Boss

Dualcaster Mage

Sevinne's Reclamation

Hammerhead, Maggia Boss

How it works

1. Cast Sevinne's Reclamation by paying its mana cost, targeting any applicable target.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Sevinne's Reclamation.
4. Holding priority, activate Hammerhead by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Sevinne's Reclamation, with the copy targeting Dualcaster Mage
6. Resolve the Sevinne's Reclamation copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This loop begins when you cast Sevinne's Reclamation from your hand and flash in Dualcaster Mage in response to copy it, targeting the Mage itself with the copy. By utilizing Hammerhead, Maggia Boss as a sacrifice outlet, you can send Dualcaster Mage to the graveyard just in time for the resolving copy of Sevinne's Reclamation to pull it right back onto the battlefield. This continuously triggers Dualcaster Mage's copy ability and grows Hammerhead, Maggia Boss with endless +1/+1 counters.
