You can do whatever you want with your card, I'm just offering suggestions.
I 'm not going to use any kind of logical justification, however, until someone explains to me why casting Explosion on Unstable Gas does not ignite it I don't remember who said this, but apparently you are detonating it out of it's blast range.
When compared to Ash Eater, Photon, etc, I like it. It doesn't take the same route with generating quanta and rather offers a potential rush (especially with Fractal) which works well with the anti-CC mechanism (You have an Otyugh? That's right, go kill that Otyugh by eating poisonous spiders).
Seems good to me, although I kind of find it funny that this card would be OP before the 1.27 changes to Dragonfly and Gnome Gemfinder were announced.
