I don't think otyughs are necessary since one major goal of this deck is to keep your opponent's quanta so low they can't play any creatures. Sure they usually get some out eventually, but by then it's too late. And using gravity pull is on my to do list, but I've been focused on other things since creating this deck. You're welcome to try out different things though.
I'll explain the current version though. The dragons are your main source of damage (obviously). You don't need too many though because your discords do six damage. Four discords seems to be perfect for this deck. I seem to almost always have one out by turn two, most of the time by turn one. The gravity towers ensure you'll get the quanta you need to use your black holes if you face a deck with devourers or get a discord stolen (before I added them those decks were a real problem). The momentums are the exchangeable cards, I find them useful though because you can still kill your opponent if they manage to get up a good shield, and when you place them on flying discords their effect isn't stopped. And the animate weapons need no explaining haha...
Anyway, you always want to get out a discord asap; otherwise, a dragon. If you're going up against a rainbow, discord doesn't help all that much as far as its effect goes (sometimes it does more harm than good), but the six damage is nice and cheap. If you get a good start and they get a bad start, use your black holes to keep them from playing anything. If you both get good starts, you might use one or two black holes early to gain a little advantage, but save the rest in case it gets ugly. If you get a bad start, regardless of what they get, just do what you can. It's a judgment call if you want to either slow them down or save your holes for healing. That's pretty much all the strategy to this deck, except for some special circumstances, but those are far and between.
