Together Forever + Ashnod's Altar + First Day of Class + Phyrexian Walker

Together Forever

Ashnod's Altar

First Day of Class

Phyrexian Walker

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