Then, like I said, why don't you use a Lobotomiser? Low cost, high damages, the ability is very useful, and aether quanta aren't used. And, you said that air and life quanta are already used, but death too, with the chrysaora ability (and also, the cost of the Druidic staff is only 2
, and it greatly improve the victory rate/EM rate). I understand for the Owl Eyes, i didin't see its cost when I posted. I used a version of it with the Lobotomiser, works fine and stop all the monsters with irritating abilities, like the oty).
P.S: With this deck, I always (well, almost u_u)finished the opponents within 8 turns, which means arsenic can only make to 5/6 poison max. In this case, Lobotomizer is still better.
