I would think you need to get every single card. But in case I'm wrong, theres a REALLY easy way to figure that out.

1. Start by unlocking the different cards, once you have one Tombie, Mombie and Bombie unlocked for Vegas, move on the Houston and repeat that process. Incase you dont get a skill card, proceed to 2.

2. Now start by unlocking one Tombie, Mombie and Bombie card from Stage 2, 3 & 4 in Vegas, then do the same in Houston. Still no skill card?

3. You have now eliminated the easy ways of obtaining the cards, and in no way shape or form have you delayed yourself, since the cards you unlocked previously will only benifit you now, since you have less to unlock. Have fun.
