Bump it up.
Gotta have the wild cards. I think that the WC most important feature is that if you have 5 cards, you can almost certainly cash two turns in a row. This goes really far strategy wise, because you may take your turn very differently if you know you will be able to cash this turn and next turn, versus the uncertainty you will get that card you need for next turn.
If people dont like them, just make it an option like fog of war
