Stalwart Successor + Kithkin Spellduster + Bartolomé del Presidio

Stalwart Successor

Kithkin Spellduster

Bartolomé del Presidio

How it works

1. Activate Bartolomé del Presidio by sacrificing Kithkin Spellduster
2. When Kithkin Spellduster dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Kithkin Spellduster enters, Stalwart Successor triggers, putting a +1/+1 counter on Kithkin Spellduster
4. Resolve the Bartolomé del Presidio ability.
5. Repeat.

This clever little loop turns the persistent nature of Kithkin Spellduster into an endless engine by continuously cycling it through the graveyard and back to the battlefield. Every time the Spellduster returns with a -1/-1 counter from its persist ability, Stalwart Successor steps in to neutralize that penalty by placing a +1/+1 counter on it, which simultaneously satisfies the condition to negate future counter-cancellation. Meanwhile, Bartolomé del Presidio acts as the dedicated sac-outlet that fuels the entire sequence, growing larger with every iteration while triggering endless deaths and entering-the-battlefield events.
