Meh.... It only gets counters with no trample, no way besides recasting it as a commander to get bigger. It has recursion but you are going to need important creatures with ETB triggers in your graveyard for this to work. Then you are forced to attack to get a token of said creature that gets exiled at the end of turn. You'll want to dump counters on this creature because getting back bigger stuff by letting it die to recast it for more mana will take longer and you are going to want creatures in your graveyard.
So you have cast commander, attack with commander, recursion in graveyard. 3 hoops to
jump through just to get another ETB from a creature from graveyard. Then creature in graveyard has to meet said condition of having less power then the commander to come back. That to me seems a bit much to use/abuse your graveyard.
This card I can see as part of the 99 but not as a commander.
