Adding Expansions?

[Nerftw]

It's probably not a good idea to just mix More Good Cards directly into your deck unless you have a lot of other expansions. It even warns you about this in the instructions.

I only put about half of them in a Munchkin 1 + 3 deck, and it was still watered down too much. (Everyone had nothing but wandering monster cards and enhancers, and no monsters to even fight.)
