The 3 combo pieces

What must be in place

Elemental Mastery attached to Devoted Druid.
Devoted Druid does not have summoning sickness, and has a power of one or greater.

How to execute it

  1. Activate Devoted Druid by tapping it, creating at least two 1/1 Elemental creature tokens with haste.
  2. When the Elementals enters the battlefield, Cathars' Crusade trigger that many times, putting that many +1/+1 counters on each creature you control.
  3. Activate Devoted Druid by putting a -1/-1 counter on it, untapping it.
  4. Repeat.
  5. If Devoted Druid has a power of two or greater, you then get infinite +1/+1 counters on Devoted Druid, which you may use to activate its mana ability instead to get infinite {G}.
