Dualcaster Mage + Faith's Reward + Bartolomé del Presidio

Dualcaster Mage

Faith's Reward

Bartolomé del Presidio

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 Bartolomé del Presidio 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 elegant loop turns a graveyard recursion spell into an infinite engine by leveraging Dualcaster Mage's clever entry trigger to continuously copy itself. As Faith's Reward resolves over and over, it plucks the Mage straight out of the graveyard every time it is put there, ensuring the loop never runs dry. Meanwhile, Bartolomé del Presidio acts as the sacrificial altar that sends the Mage to the graveyard in the first place, growing its own power with +1/+1 counters while cleanly closing the loop.
