Well if I told you what cards I use for melee then I wouldn't be unique anymore, lol. Was pretty simple for me, as I used to do a lot of theory crafting on ESO but I digress, I would say record a couple of your fights. Play them back and figure out why you are losing. Are you landing more punches but not winning?- (invest in damage cards), are you taking less punches than your opponent but dying faster?- (invest in healing abilities) my abilities work for my play style, they may not work for yours. Ability cards in my opinion are maybe a quarter of the reason I'm the current RDR2 Fight Club Facebook group Champion (PS4). Technique is the biggest part of fighting but if you wanna learn more you can send me a friend request PSN Rusto321 I'm also admin on Rdr2 fight club PlayStation community. If you wanna go fighting hit me up
