Personally, I'd shift some of the Invoked ratios, you don't need 3 of the Fusion Spell, 2 suffices well enough. Also, I'd find room for at least 1 Terraforming, since you can toolbox field spells a tad.
Is there something else I could tech in instead of invoker stuff. Meta is really fast these days for Crystal Beasts. I don't know how they work in OCG with their support though but those pendulums do seem neat.
