I find two things about this card that are unclear:
1. Does your quanta pool before the capacitor go into the capacitor? If so, is it doubled before putting it in?
2. Is the quanta you generate displayed? If you have QTs and don't know the values on it, it's completely impossible and you don't know what will happen when you release it.
Other than those two things, I really like the idea of the card. It seems very balanced.
