Rate my Pokemon Diamond/Pearl Team! Please?

well your team is OK i don't really feel like reading and looking and telling you some mistakes but two i can tell you off hand is get rid of tyranitars sandstorm his special ability should make a sandstorm start anytime hes in battle so that's a wasted move also get rid of kyorgers sheer cold eventually you ll fight people stronger than you and its also not very accurate so it wont always work ans maybe get rid of surf and waterfall now that i think about it surf can hurt your own Pokemon unless you have a Pokemon with the special ability of dry skin or u use protect or something and waterfall on a very strong Pokemon seems like a waste to me man i keep looking at you team yeah cuts a waste for groudon you want moves that reflect your Pokemon's types and look towards whats stronger there special attack or physical attacks and getting moves that are there type like for instance fire or ground for groudon and giving him a move that can be a physical ground or fire attack cause he will get a boost and cause even more damage sorry to tell you that your team is like maybe a 2 out of 5 you have strong Pokemon but your wasting there talents with useless moves
