Workhorse + Together Forever + Communal Brewing

Workhorse

Together Forever

Communal Brewing

How it works

1. Cast Workhorse by paying 6, causing it to enter the battlefield with four +1/+1 counters plus an additional +1/+1 counter of each ingredient counter on Communal Brewing.
2. Activate Workhorse by removing a +1/+1 counter from it, adding C.
3. Activate Together Forever by paying 1, targeting Workhorse.
4. Repeat step 2 until Workhorse dies as a state-based action due to having 0 toughness.
5. When Workhorse dies, Together Forever triggers, returning Workhorse from your graveyard to your hand.
6. Repeat.
