"No, cause you aint a MASTER, (yet)" - Oh, yes, and that one too.
And about deck definition:
-Cards from one element need up to 12 kinds of mana (think fate egg or mutants). Is that mono?
-Decks that use only one kind of mana can use cards from light (photon), air (animate weapon), fire (immolation), time (upped sundial) and so on. Is that mono?
So do I have to limit myself to both mana use and card origin to be mono? And what has this definition to do with how the game is played? Why exclude animate weapon from mono, when clearly every one-mana-kind-only-deck can and will use it? Just to make the typical deck an actual player uses a dual deck by definition?
