I don't want to recreate your card but how about this:
1) Card is played and has adrenaline instead of momentum (more
- like)
2) Unupped gets changed to 2|2 and Rhinos gets changed to 2|2, but only two are played
3) Upped gets changed to 3|3 and Upped Rhinos are played that are now 3|3, but still only two are played
I feel like this should also make the card cost for unupped should be 4
while the upped stays the same.
Other than that, this is pretty cool.
