How it works

1. Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Cast Sensei's Divining Top by paying 1 and removing a counter from a creature you control.
3. Managorger Hydra and Glaring Fleshraker's first ability trigger.
4. Resolve the Managorger Hydra trigger, putting a +1/+1 counter on it.
5. Resolve the Glaring Fleshraker trigger, creating a 0/1 Eldrazi Spawn creature token.
6. When the Eldrazi Spawn enters, Glaring Fleshraker's second ability triggers, dealing 1 damage to each opponent.
7. Activate the Eldrazi Spawn by sacrificing it, adding C.
8. Repeat.
