Rite of the Wildform

Rite of the Wildform can be your commander.
At the beginning of your upkeep, you may
remove all ritual counters from Rite of the
Wildform, search your library for a creature card
with converted mana cost equal to the number
of ritual counters removed this way, and put it
onto the battlefield. Otherwise, put a ritual
counter on Rite of the Wildform.
