showdown bro. i can teach you what i know but its very hit and miss compared to my bw game because fairies/megas/type mechanics have changed the way the game is played. tends to be about trading off powerful attacks, blow for blow and not so much about playstyles dominating, but individual pokemon stepping up to the plate; ie bisharp is incredibly good this gen because stab knock off, key resistances and defiant helps keep intimidate users well away.
