Name: Burden
Element: Gravity
Type: Permanent
Cost: 4
Effect: Increase the ability cost of all cards by one while this card is in play.
It would be a good way to slow down your opponent if they rely on abilities. It effects both players and it doesn't stack, so the cost is low. It's similar to nightfall though, so making it cost three quanta to play would probably still be balanced.
The upgraded version would just cost less.
