I want to new birds, new spell cards and possibilities to may 2 cards with the same bird!
And cooperation beetween 2 players

@deaftalk, I know this, because I have three complete sets and gold slingshot;)

You can buy one at time. But slingshot will improved when you complete the entire set.

Each set will improve the slingshot. So if you only have a crown set or street set your slingshot’s level is Silver. If you have both, the slingshot is gold.

I’m just looking for facebook friends for this game too.

I agree. I hate this system.
