So I had an idea for an EDH format variation, and thought I'd seek feedback on the idea. I call it Tiny Partners.
The premise is simple: choose any two Legendary Creatures any
rarity, under 3 CMC, to serve as your Commanders. They are considered to have partner with each other and only each other for the sake of the format. The other 98 cards in the deck will be singleton (other than basic lands,
wastes and snow covered basic lands. The other 98 cards are also limited to common and uncommon
rarity and must stay within the color identities of the Commanders.
