As many have suggested: More cards is always the way to go- within reason. If you can manage it- user edited cards, or even user submitted cards with votes (e.g., 'only allow cards with a certain score in your game)... would be brilliant. Difficult, but brilliant. if possible, said score would have to be a function of both votes number and rating, so a 4/5 score from 2k people exceeds a 5/5 from say... 3. That being said, the game needs a few tweaks. it works- such as it is, but needs more zing. There's an online cards against humanity game already, and apples to apples is more of a family/cross generational game. That said- you need to step it up if this is to succeed!
The increase in score that supplements give (multiplier) is increase. When you unlock (totally not) Steroids, you get x4 money; Whey Protein is a mere x2 money
