I've been looking through all the cards.. and a Void Rush Deck is hiiiighhhlyyyy capable, and unstopable.
I feel that allowing your opponent to pick which quanta the void plays give, (if code-able) would even out the effects of the Void cards muich better.
Void cards shouldn't be able to be fractal'd.
All Void cards need to not be immateriable.
Just my opinion.
