I think a better version of this card is possible.
How about it burns quanta whenever quanta is spent?
Sure, I've got an idea on the forums right now somewhere that causes a player to take damage whenever he GAINS quanta.
This card could cause the player to 'pay more quanta' to play cards?
Eg.
Toxic Flames
Cost: 5

Type: Permanent
Ability: For every quanta your opponent spends, he loses 1 additional quanta.
Notes: If your opponent has no additional quanta, he loses 1 life.
Toxic Flames
Cost: 4

Type: Permanent
Ability: For every quanta your opponent spends, he loses 1 additional quanta.
Notes: If your opponent has no additional quanta, he loses 1 life.
What do you think?
ps. Hopefully Coinch gets back to me, otherwise I'll post this as a new idea but credit him for it :p
