Cresselia @ Leftovers
Trait: Levitate
EVs: 252 HP / 252 Def / 4 SpAtk
Bold Nature
-Rest
-Sleep Talk
-Calm Mind
-Ice Beam
This guy is designed to be a Comeback Kid, not a midgame tank or sweeper. CM up as soon as your opponent's Bug/Dark/Ghost types are safely gone, and begin the wreckage. Toxic got you down? Rest clears status and with Sleep Talk, you can still get either more boosts off or fire off the not-often-resisted Ice Beam at +whatever. Then, once you awaken, either rest off the sustained sleeping damage, or boost, or fire off again! It's very trolly, but it really does work.
I know sometimes I post sets that don't seem to work 100% of the time, but this one works better than CM Moonlight Cress in the sun, as it can't be worn down with Toxic or Burn, which was the bane of CMCress.
It pairs well with a heavy offensive threat like Kyub or DeoA, as the opponent will focusfire at it instead, leaving Cress to slowly and silently become a Behemoth.
Threats to this set?
-Suckerpunch SD Bisharp
-CB Bug Bite/U-Turn Scizor
-Darkrai
-TTar
-Scarf Landorus carrying U-Turn
Hitmontop would be a fantastic partner to this set, killing off most of these threats, as well as Steel Types that resist Ice Beam. Cress can kill off any Flying types threatening Top, like Tornadus-I and Crobat (seeing quite a few of them lately.) You can also run Chandelure to take care of walls and Bulky Psychic Types, though Top would still be needed for the Dark Types.
