CCG Toolkit | Multiplayer Card Game Framework

Hello!

I’m working on a new currency system for the toolkit, but there is so much integration of the Mana system, I’m struggling. I just want to build a system that stacks based on how much you don’t use, not based on player turn. I want the player to gain 1 Mana each turn, but once they use it, it is gone.

Further break down:
Turn 1 : you gain 1 Mana. Play a 1 cost. You now have 0 Mana.
Turn 2: you gain 1 Mana. Now you have 1 but you save it.
Turn 3: you gain 1 Mana, now you have 2 total. You play a 2 cost card. You now have 0 Mana.
Turn 4: you gain 1 Mana. You now have 1 Mana to spend. Etc etc.

Any one can help with this framework?
