Welcome to the card suggestion section of the forum.
This seems to be your first card.
This is a very fun yet simple card. I can imagine the art of this card being a weird looking gambling machine.
But it is a bit too luck based and may not yeild a good effect for the cost paid. I would change " Gain 0 to 7 quanta " to " Gain 3 to 7 quanta ". (Unless you are seriously about making it a risk taking gamble card)
Also imo you should remove the Invisible,Immaterial effect on the upped card. I don't understand the advantage of being both invisible and immaterial at the same time, as being immaterial already makes it impossible to do anything against it. Also there does'nt seem to be an advantage to surprise the opponent this card with invisiblity.
This card needs some major fixing before anything else need to be taught. Fix them and this could turn out to be a great card. Good Luck.
