Your Pet Commander

Before the game begins, you may reveal Your Pet Commander from your command zone. If you
do, head to EDHRec.com and choose a legal commander whose rank is 250 or lower. Your Pet
Commander becomes a copy of that card perpetually. (The highest rank of commander is 1
and is measured by number of submitted decklists.)
Once you give people the freedom to do whatever they
want, as the Lord found in the Garden of Eden, they
will do exactly that.
