... Can you please explain me you are supposed to play the Mirror Shield in the Firebolt deck without having any way of generating Light quanta?
There was supposed to be a nova in there, sorry about that. added it now
for anybody curious as to why it's in there, it's necessary to beat anybody with a shield that reflects spells (there are four of them, I forget which)
if the opponent has a reflecting shield, you simply put yours up and target yourself, which bypasses the opponent's shield
