The 3 combo pieces

What must be in place

Ghave has at least two +1/+1 counters on it.

How to execute it

  1. Activate Ghave's first ability by paying {1} and removing a +1/+1 counter from it, creating a 1/1 Saproling creature token.
  2. Rosie triggers, putting a +1/+1 counter on Ghave.
  3. Activate Ashnod's Altar by sacrificing the Saproling, adding {C}{C}.
  4. Repeat.
  5. Once you have infinite mana, you may forego sacrificing the Saproling tokens to Ashnod's Altar, and then use Ghave's second ability to put infinite +1/+1 counters on creatures you control.
