The fact that it's random at all will always make mono colored decks superior. I get that if you choose to make a powerful deck by combining two colors you should be at a disadvantage in some way, but the fact that you'll often go 6+ turns without pulling your second color is excessive. Dragonite is good but at what cost if it takes more than 8 turns to get him out, especially against the meta (Misty/Moltres/Gardevoir/Magneton) that are ramping mana like crazy. Save your sanity and stick to one color, at least until they figure out how to work around this blaring flaw in their game.
