Ashnod's Altar + First Day of Class

Ashnod's Altar

First Day of Class

How it works

1. Cast First Day of Class by paying 1.
2. Activate Ashnod's Altar by sacrificing the persist creature.
3. When the persist creature dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
4. When the persist creature enters, First Day of Class triggers, putting a +1/+1 counter on the persist creature.
5. Repeat from step 2
