I was there too.. i love the piranha and i had 4 piranha's + the police dudes, but then i wanted a change so i tried to change to Sakrohm or whatever, and now im doing 4-4 and it works awsome..
zhudac has a point and is just trying to help.
There's a reason why cards are usually banned from All Stars in Elo. Because people don't like facing them cause they're good. Sure, Striker and Marina aren't in budget, but that's two cards out of a whole clan. Try saving for Jessie, Stacey, Randy, and like Oyoh depending on star count.
You could always just stick with mono
