Stalwart Successor + Woe Strider + Lesser Masticore

Stalwart Successor

Woe Strider

Lesser Masticore

How it works

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