No Guard for the win!
I think No Guardwould be a good ability. Your moves would always hit at the cost of all the opponents moves hitting. This could be used to gain momentum. Excellent revenge killer if it could be given a scarf. Overall, I think there is not much, if not, then no risk in moxie. Illusion would be my next choice but my one choice is the No Guard.
A true battler wins with Magikarp.
