Well, Nice Team, but you could correct some small mistakes. You should Put Naughty Nature (+Atk, -Def) on Tyranitar, and put 4 Special Atk EVs, but anyways. focus sash isnt very great, suicide weather lead is very stupid, and could ruin your team, and you dont have any Pokémon to setup Stealth Rocks. Jirachi isnt very effective at Scarf, and depending of rain, is stupid, you could switch if for Gastrodon, that could be your special wall, since you tyranitar is suicide, it absorb water / eletric like a boss. On Keldeo, Hidden Power eletric is more usefull, hitting Jellicent and Tentacruel. But if you put gastrodon, you could swap if for other special sweeper, like Reuniclus. Another Choice in Team? You should have other physical wall, since gliscor is offensive. You could Use Donphan, or Skarmory, or A good other choice is Life Orb Genesect (Timid Nature, 4 HP, 252 Special Attack, 252 Speed) With Bug Buzz, Flamethower, Thunderbolt and Ice Beam, works really well... On Salamence, i dont think its a good choice in sand, but its the best choice of all your team. Crunch is useless, Change it for Dragon Claw or Brick Break, for Air Baloon Heatran.
