There's pretty much little to no way that you'll be able to get the Dune Scorpions out in time, since you're relying on only the Mark and Novas to get your
quanta.
Some elements are overused, while others aren't utilized at all -- going 2 Unstoppable, 2 Chaos Power, 1 Improved Blessing is much more stable when the only quanta source you're using is Nova. Same goes for the creature control -- consider replacing some of the Thunderbolts with Basilisk Blood, Freeze, and Shockwave so that quanta usage is more balanced.
Also, four Explosions are excessive, and you won't be able to fuel them in time because you only have six Novas -- they'll probably end up rotting in your hand. Two should be more than enough.
