Outrider en-Kor

Task Force

Miren, the Moaning Well

How it works

1. Pay 0 to activate Outrider en-Kor, targeting Task Force.
2. Task Force triggers, giving itself +0/+3 untill end of turn.
3. Repeat steps 1-2 untill Task Force has infinite toughness.
4. Pay 3 and tap Miren, the Moaning Well, sacrificing Task Force and gaining life equal to its toughness.
