Lurking Roper

Elemental Mastery

Suture Priest

How it works

1. Activate Lurking Roper by tapping it, creating four 1/1 Elemental creature tokens.
2. When the Elementals enter the battlefield, they trigger Suture Priest's first ability four times.
3. Resolve the first Suture Priest trigger, causing you to gain one life.
4. Lurking Roper triggers, untapping itself.
5. Repeat.
