Question: We basically need 9 different commanders total right?
So I cannot run Klore in 2 of my decks?
Your decks cannot have the exact same commanders. If your first deck has three klores in command, your second deck cannot have three klores,but it can have two klores and one aberion, and your third deck cannot have three mlores or two klores and an aberion.
Its basically so your opponent can tell which deck you are using by looking at your commanders.
