As you see this is Giratina's team i made to stall out everything(Xerneas plz dont take it seriously).5/6th of my team have 252 Hp and 248SPDorDef to take mins damage.So,Basically Giratina and Mega-Sableye help to "status" my opponent and then recover/rest with sleep talk spam until my opp loses their hp.Latias is my deffoger and wish user(comes handy when's a mon is less in health) along with two hard hitting move for poison/dragon coverage.Cofagrigus is again one of the defensive wall ,its does what Giratina and Sableye do but it gets a move called "Hex"(Power doubles if the target's statused).I try to enable my move "Trick room" and then use destiny bond when my oppo's attack and I am low on HP.Goodra is my special wall but the probs is that it doesnt get defensive moves so why not offense.First 3 moves are coverage and Dragon tail to save my team from set-up-sweeper.And finally my Rockstar i mean my rock setter and Sash to ensure that it wont die before setting.If somehow my garchomp survives i used it to get last moments kills.Thats it.Poof*
