i need to think about the items but other then that its all done

Answer 1

Well, I would suggest switching Gastrodon with Floatzel or Milotic because that would be 2 Ground types. I would pick Floatzel for its Speed, which forms a perfect sweeper. You have great movesets for your team so don't switch it. As for items, here they are:

Torterra-Miracle Seed(increase damage of Wood Hammer
Luxray-Magnet(increase Thunder's damage)
Roserade-Poison Barn(increase Sludge Bombs damage)
Lucario-Life Orb(to form a perfect sweeper, increase your damage)
Driftblim-Leftovers(it has high HP, so this is a must)
Floatzel-Mystic Water(increase damage and in the rain, perfect)

Floatzel moveset-Adamant(you won't use SP Attack anyway)
Waterfall-STAB
Ice Punch-Grass types
Bulk Up-raise Attack and Defence
Quick attack/Aqua Jet-you know why
