A little advice from me use a hazard poke like ferothron its helps u to defend plus even setting rocks sspikes etc . 2nd u need a strong dragonite if possible ha required .U can get blessey for wall to protect team .u can get excadrill its do helpful in pvp .Now u need water type its ur wish if u use tank poke or offense if offense then azumarill ,tentacruel' alomomola'gyrados . I prefer azu and gyrados. and a magenzone will be good that all ^_^
