Stalwart Successor + Woe Strider + Glen Elendra Archmage

Stalwart Successor

Woe Strider

Glen Elendra Archmage

How it works

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