Blaziken @Choice band/choice scarf/Life orb/Expert belt
*adamant/jolly
Sky uppercut
Flareblitz/Blaze kick/Fire-P
Stone edge/T-punch/Brave bird
Swords dance/Brave Bird
Blaziken can pull of a sweep from the physical side, swords dance could work, but then the item should not be a choice item
Milotic @Leftovers
*Bold
Ice Beam
Sleep talk/Hypnosis
Rest/recover
Surf
Milotic does better as a wall, you could either go with rest and sleep talk, because rest makes her fall asleep, activating marvel scale, raising her defense and then just sleep talk, or if you don't decide to use the sleep set go with recover and hypnosis
Torterra @Leftovers
*Impish
Wood Hammer/Seed bomb
Earthquake/Stone edge
Leech seed
Stealth rock/Protect/Sub
Terra can tank and lay down leech seed and even stealth rock on the field, you could make it a sub seed set if you go with Leech seed and Sub, it a allows him to make a sub and leech seed and leftovers will heal the damage from creating the sub. Seed bomb is and option if you don't like Wood hammer's recoil.

trick/encore/calm mind/shadow ball
Psychic
Focus-blast
Shadow ball/G-knot
No! don't use Alakazam physically, he's a special sweeper.
Only use trick if you plan to use this competitively, the idea is to trick choice specs to a physical sweeper, making it a useless item to them or if the opportunity's just right attack them with choice specs, other wise if you're just going to use this in-game go with a set up move like calm mind or encore, with encore just use it on a non damaging move, and it will give you a couple free turns.
