Dude looks pretty cool. Not sure if he's better than some of the other commanders in his colors at what he's trying to do, but certainly different. He plays fairer politics than Rafiq of the Many in multiplayer, so there's that to consider. He probably makes Jenara obsolete though.
Quick list of existing bant commanders for reference:
Angus Mackenzie
Rafiq of the Many
Phelddagrif
Treva, the Renewer
Rubinia Soulsinger
Ragnar
Jenara, Asura of War
Arcades Sabboth
