rares cant have 6 bo and command is not what you look for
command is fine i guess... ur bo already lasts pretty long no doubt..
Also rares y cannot have 3wc sk and 3bo so 6bo... ud need to game magic (blue) base for that..
Basically the idea is that if ur helm gives like 4-5bo and ur visio is 4-5bo its not worth changin and keeping tur 4-5bo helm in cube... the effeciency it has is too minor...
