Few questions on Character card deck system

Isn't p/mdX the variable for physical/magical defense? Don't want to rush making a paladin for the card only to have it increase a useless stat like that.

Hero is physical def so pretty sure that's a negative. If i'm not mistaken, FP is magic def.

Kinda wish the deck could hold as many cards as possible. Making some of these different classes is really fun. Even if the paladin buff is worthless, I got it to 172 so far and it's an interesting class to play with. I also understand how ridiculously stupid charged blow was in the old days when it took off your charge. +1 respect for old school WKs/Paladins
