Together Forever + Ashnod's Altar + First Day of Class + Shield Sphere

Together Forever

Ashnod's Altar

First Day of Class

Shield Sphere

How it works

1. Cast First Day of Class, allowing yourself to loot once due to learn and making it so whenever a creature enters the battlefield under your control this turn a +1/+1 counter will be put on it.
2. Cast Shield Sphere.
3. First Day of Class triggers, putting a +1/+1 counter on Shield Sphere.
4. Activate Together Forever by paying 1, making it so the next time Shield Sphere dies this turn, it returns to your hand.
5. Activate Ashnod's Altar by sacrificing Shield Sphere, adding 2.
6. Together Forever triggers, returning Shield Sphere to your hand.
7. Repeat.
