For the pokemon, it needs some setting up to get the motion going.
Toxicroak @ Life orb
Adamant
Dry skin
[252 atk / rest can vary]
-Swords dance
-Sucker punch
-Taunt
-Brick break
So, this is how I came about this set. Switch in toxicroak on a wall under rain and either swords dance or taunt. From that point you have the option of swords dancing again or just straight out sucker punching the target if you know it will attack you. Taunt eliminates toxicroak's vulnerability to status inflictions and it also helps sucker punch work more often. As for the last moveset, I wasn't really sure what to put on, but I used brick break for stab and blissey (which btw, has just about nothing on toxicroak if it is standard uberbliss). As you may see, toxicroak has a major psychic attack weakness, but good thing in ubers, psychic attacks are almost nonexistent. Toxicroak makes a great anti toxic spikes addition as well.
Damage calcs from toxicroak's sucker punch after 1 swords dance:
Max hp/def giratina (+def nature): Damage: 54.96% - 64.68%
Min hp/def mewtwo (neut nature): Damage: 134.56% - 158.07%
Min hp/def latias (neut nature): Damage: 157.81% - 185.38%
Max hp/def deoxys-d (+def nature): Damage: 74.01% - 87.17%
Min hp/def kyogre (neut nature): Damage: 69.50% - 81.82%
Min hp/def rayquaza (neut nature): Damage: 67.52% - 79.49%
Min hp/def palkia (neut nature): Damage: 67.60% - 79.75%
Max hp/def lugia (+def nature): Damage: 62.98% - 74.28%
Damage calcs from toxicroak's brick break after 1 swords dance:
Min hp/def Darkrai (neut nature): Damage: 237.72% - 279.72%
Max hp/def blissey (+def nature): Damage: 154.76% - 182.21%
Min hp/def groudon (neut nature): Damage: 67.16% - 79.18%
Max hp, 32 def groudon (neut nature): Damage: 55.45% - 65.10%
Min hp/def dialga (neut nature): Damage: 153.67% - 180.94%
Min hp/def arceus? (neut nature): Damage: 137.53% - 161.94%
Just eyeballing these calculations, after a layer or two of sr/spikes, toxicroak is set to ohko most of the listed ubers. Also, an interesting part of toxicroak is that it recovers some good hp every turn from supporting rain, and its fire weakness is neutralized in rain as well. Also, I also forgot to mention that once sleep clause binds out darkrai's dark void, toxicroak is a good switch in. Of course, some ev investment needs to be considered. If you want to match speeds with dialga and the like, you need to max speed. If you don't, then adding sp def evs will help too.
