Oh my gawd... that Tropius. xD I might have to make an Ubers sun team just to test that out.
All right. I have one. It's called f*kin' Charge Beam Mewtwo.
Mewtwo @ Life Orb
Ability: Pressure
Timid Nature
EVs: 4 HP / 252 SAtk / 252 Spe
- Psystrike
- Aura Sphere
- Ice Beam
- Charge Beam
I created this puppy as an alternative version of a 4-attacks LO Mewtwo that I had been using on a Groudon team (had Fire Blast in place of Charge Beam).
The selling point of his set is picking up a KO while setting up, without needing to take a turn to do so during which you can be counterattacked. I often send this guy out on a weakened Kyogre or Darkrai or something that he can definitely outspeed, pick up the revenge kill with Charge Beam, and proceed to use him like a regular LO non-CM Mewtwo. The first three attacks offer coverage on everything important in Ubers save other Mewtwo, which can be handled with +1 Ice Beam. It loses out on the SDef boost that contributes to CMtwo's bulk and consequent deadliness, but it trades it for the ability to set up and nab a KO simultaneously. It's slightly luck-based as far as picking up the boosts goes, but it CAN function without them as 4 attacks Mewtwo normally does, and the risk is mitigated by the possibility of getting to +2 or +3 (which is really just overkill on most things).
