Thanks for the info :) is bulky sd techniloom viable? But anyway, which set is the best atm?
As for the dragons, i dont have anything to really ask anymore other than: which latios set is better, lo or specs?
Edit: also, can hydreigon take the role of lati@s as an absorber and reliably fast destroyer?
1) no, technician breloom is not bulky and it never will be. the only reason to run a "bulky" variant of SD breloom would be to go for two swords dances before sweeping... good luck with that cause it's never gonna happen. you can shift EVs from speed into special defense or HP if you want to take like one hit to avoid being checked by whatever, but you're not gonna have the bulk to set up multiple SDs, you need poison heal for that and there's no reason to run SD poison heal breloom. that's a pipe dream.
2) neither one is better, this depends on your team
3) hydreigon is 12 base speed points slower than lati@s, which is a complete and utter kiss of death in a metagame that centers around 108+ speed tiers. it also trades a pursuit weakness for a fighting weakness. so no, it is not at all a viable replacement and it does not fill similar roles
Almost all Life orb tornadous T has the same 3 moves with hurricane, u turn, and focus blast/ superpower. I have seen sleep talk, tailwind, taunt, rain dance, and once I saw Hp ground for the fourth and final move. I want to know the best one for a team that has trouble with Breloom and sun teams. I have experimented with them and saw that with my playing style, there was no superior option. In your guy's opinions, which one is the best.
against breloom, sleep talk is probably the strongest option. you can blind switch in on a breloom and no matter what it does it can't touch you - unboosted, it can't kill you, and you can kill it literally in your sleep if you come in on spore, so it can't risk boosting either. specs tornadus-T happens to abuse this move particularly well since most hidden powers are fairly weak and highly prediction-dependent, meaning it doesn't usually have better options. against sun in general, rain dance is generally better. most of sun's hurricane resists, if it even has any, can be swept away by boosted water moves. you can then rain dance on a predicted ninetales switch and wreak utter havoc with tornadus for a few turns.
Are there any other speed boosting sweepers for the rain other than agility Thundy T?
if you want a pokemon that actually uses a speed boosting move and can "abuse rain", agility thundurus-T is by far the most viable and the best. it helps that thundurus is a really underprepared-for threat and a lot of teams are subtly weak to it. tornadus-T is rain's best pokemon and hands down the best pokemon in OU, but there's really no good reason to run agility on it. landorus (either forme) can abuse rock polish well but it doesn't reall benefit much from rain. you have some +1 speed boosters as well such as volcarona, miscellaneous dragons, but none of these are especially distinguished in rain (hurricane volcarona is notable for being a threat to sun).
