this set is for b/w and is great but does rely a little on special attack but could be physical attacker but lets get to the moves
item/ leftovers ability torrent which means water moves boost 50% when the Pokemons at red or low yellow hp
252hp 102sp.atk 75def 75sp.def 4spd
scald, hydro pump -scald can burn its STAB 80 base power its a special move as well as HYDRO PUMP is 120 base power which is just op and very good offensivly overall I reccomend scald cause it can burn
rapid spin-get rid of stealth rocks spikes toxic spikes sadly only 20 base power not very strong
HP (hidden power), ice beam-i would recomend grass or fighting other than that this set is a little offensive ice beam to take on dragons or to take on grass types
toxic-AMAZING move poisens and builds up more and more damage each turn and I said this is an offensive set
