Same with Commando and Forced Bi? Same card, one is cheaper. I think you should change one of them, but I don't immediately have any suggestion to what.
My plan with a lot of these better versions of the same card are to implement a rarity system, so you might have, say, a 5% chance of the rarity of Commando, and a 1% chance of the rarity of Forced Bi. I believe that implementing a rarity system on rewards will greatly improve balance and variety.
