Crystalline Crawler + Gideon's Sacrifice + Vigor + Scourge of Kher Ridges

Crystalline Crawler

Gideon's Sacrifice

Vigor

Scourge of Kher Ridges

How it works

1. Cast Gideon's Sacrifice by paying , causing all damage that would be dealt this turn to you or to permanents you control to be dealt to Crystalline Crawler instead.
2. Activate Scourge of Kher Ridges's first ability by paying 1, dealing 2 damage to each creature without flying.
3. Gideon's Sacrifice redirects damage to Crawler, which results in at least three +1/+1 counters being placed on it instead due to Vigor.
4. Activate Crystalline Crawler's first activated ability at least twice by removing at least two +1/+1 counters from it, adding at least 1.
5. Repeat from step 2.
