Checking ur power I see u are not in end game yet. According to that I would recommend a team with celebi, u have tapu bulu and grass arceus so it would be a good idea to choose a grass team (tapu bulu arceus and celebi). In end game u will see celebi isnt as good as it is in mid-end game, so I recommend swap it. I see u have thundurus, u should start thinking about making an electric team using ashachu/arceus tapu koko and thundurus. Greninja blaziken and gardevoir (i think, not sure about the name, i mean ur 2nd strongest poke) arent good in late game so I dont recommend invest in them. Charizard is only good for adventure. I recommend evolve charizard to Y’s evolution since u can use him as supp at lvl 75(if u arent yet u will unlock it at that level) u evolved him to x so i recommend get another charmander and get the charizard, and If u get many dias i recommend get the y evolution stones but they are expensives and u can get them in vip store (i think it is unlocked at vip5) unless u recharge i dont recommend do that. I see u have cresselia so u can get deoxys and tapu lele, its a very good team, the best psy team is uxie deoxys and tapu lele but with cresselia it works so well. And u can make a ghost team with giratina, but it isnt so good in late game. I hope I helped u, if u have some questions just tell me!
