Dualcaster Mage + Faith's Reward + Carrion Feeder

Dualcaster Mage

Faith's Reward

Carrion Feeder

How it works

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

This clever loop relies on Faith's Reward to constantly drag your sacrificed permanents right back out of the graveyard, turning the battlefield into a revolving door. Carrion Feeder acts as the vital engine for this cycle, giving you a free sacrifice outlet to send Dualcaster Mage straight to the graveyard just in time for the spell to retrieve it. Meanwhile, every time Dualcaster Mage re-enters the battlefield, its triggered ability steps in to copy Faith's Reward all over again, sustaining the chain indefinitely and growing your Carrion Feeder into a colossal threat.
