Together Forever + Ashnod's Altar + First Day of Class + Ornithopter

Together Forever

Ashnod's Altar

First Day of Class

Ornithopter

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 Ornithopter.
3. First Day of Class triggers, putting a +1/+1 counter on Ornithopter.
4. Activate Together Forever by paying 1, making it so the next time Ornithopter dies this turn, it returns to your hand.
5. Activate Ashnod's Altar by sacrificing Ornithopter, adding 2.
6. Together Forever triggers, returning Ornithopter to your hand.
7. Repeat.
