I do hate that you can't replay missions, though I understand why.

Though Weenie Beanie and Cardboard Robot Zombie CAN be paired well with other zombies. There's a basic card and a premium card that either benefits from, or can benefit the other card. You'll know what they are when you get them.

Also, crafting/getting cards is easy, heroes are not. I spent a few days getting 1,000 gems, and I didn't get a SINGLE hero from the multipack. I got 2 legendaries, but I'm still angry.
