Similar to suicide leading with stealth rock, is there any additional merit to the suicide setup weather pokemon now, especially since there are lots of new pokemon who can destroy with the support? This sort of two-pokemon setup fits with the new idea of just having a weather core as opposed to a weather team, and I imagine it will be much more dynamic due to the ability to pull out this suicide setup at any point in the match rather than leading with it.
For instance I've been toying with the idea of this Jumpluff:
Jumpluff @ Focus Sash
Ability: Chlorophyll
EVs: 252 HP / 4 Def / 252 Speed
Jolly Nature
-Sunny Day
-Sleep Powder
-Stun Spore
-U-Turn
Pretty much the same as any other double powder set, except Jumpluff is the fastest user (boosted to unrivalled speed with chlorophyll) and also gets to set up a Sunny Day for a pokemon such as CharX who can then start destroying an already crippled team. This Jumpluff uses the speed boost from its own Sunny Day to ensure it can outspeed and use its double powders before handing over to the powerful sun sweeper. U-turn can be used after the sleep powder instead of stun spore so you can keep momentum as they inevitably switch.
The pairing is effective as Jumpluff will happily eat resisted water type attacks from choice band azumarill (20-24% from CB aqua jet and 40-48% from CB waterfall), outspeeding it and putting it to sleep after taking a hit. Similarly he outspeeds the other two pokemon who resist CharX STABS, Heatran and Carbink. Both are slower than Jumpluff and cannot use priority to take out its last 1hp so will be slept. Jumpluff also avoids all ground type moves aimed at CharX and can survive a stone edge from hippowdon + prior stealth rock damage as long as it doesnt crit.
Anyways, I guess what Im asking is- are the new weather threats of this generation powerful enough to warrant dedicating a pokemon to manually setting up weather for them? Auto-weather inducers like politoed and CharY seem to work good still, but to me they almost feel like they set up weather for their own attacks rather than as team support.
