Hello, I am here with my first RMT on these forums. I made this rain team the other day to see if rain was good and the results have been very good. But I still need some feedback.
Politoed @ Damp Rock
Ability: Drizzle
EVs: 248 HP / 252 Def / 8 SDef
Bold Nature
-Scald
-Toxic
-Perish Song
-Encore
This is well the standard Politoed. This Politoed is there to get up the rain, try and burn stuff with Scalds. I like having Encore to trap a lead into doing a set-up move, or a hazard move which can come in handy for Politoed waring down that mon with Scald, or using Toxic to get that small damage every turn. Perish Song is for something you know will setup a boosting move that otherwise cannot be handled by this team. Or you can use this to force a switch out.
Tornadus-Therian @ Assault Vest
Ability: Regenerator
EVs: 24 Atk / 232 Speed / 252 SAtk
Hasty Nature
-Knock Off
-U-Turn
-Hurricane
-Hidden Power [Ice]
I'm in the rain. I would want to have something to have Hurricane. I had ended using Tornadus-Therian for a few reasons. It's insanely fast as a mon that 121 base speed allows it to damn near outspeed every OU non-scarfed pokemon. I also wanted to have a Knock Off user to cripple down the boosts or recovery from items to ensure for easier KO. Hidden Power Ice is coverage for this set.
Thundurus-Therian @ Choice Scarf
Ability: Volt Absorb
EVs: 252 Spd / 252 SAtk / 4 SDef
Timid Nature
-Thunder
-Volt Switch
-Hidden Power [Flying]
-Grass Knot
Standard Thundurus-T set with a little twist. STAB HP Flying! I like using it to cause majority of its switchins to either 2HKO / 3HKO them. And it also gives me protection against grass types that wall this set hard.Take that Mega Venusaur! Thunder & Volt Switch are electric STABs. Grass Knot was there to handle Ground / rock types that can give this team a small problem.
Kingdra @ Life Orb
Ability: Swift Swim
EVs: 252 Atk / 252 Spd / 4 Def
Adamant Nature
-Dragon Dance
-Waterfall
-Iron Head
-Outrage
Once Kingdra gets up like 1 Dragon Dance... Things begin to just die. Not alot of things are a safe switch in on Kingdra while its using its STABs. I put Iron Head as a coverage against fairies but STAB + Rain boosted Waterfalls kinda do more than a SE Iron Heads. I might consider putting a Lum Berry over Life Orb to not be confused after I use Outrage. I'm not to sure however.
Mew @ Damp Rock
Ability: Synchronize
EVs: 248 HP / 212 SDef / 50 Def
IVs: 0 Attack
Calm Nature
-Will-o-Wisp
-Rain Dance
-Softboiled
-Psychic
I really needed a backup rain user. And I wanted to see how Mew would do in OU since it recently got bumped up there. Truthfully, now I am debating on putting Rain Dance on Kingdra so I can give this Mew Defog and or Taunt. Then I more better support from Mew. I am also thinking of putting Seismic Toss in to get off 100 HP of fixed damage on the opponent but then I would be really open to Ghost attacks.
Mamoswine @ Focus Sash
Ability: Thick Fat
EVs: 252 Atk / 252 Spd / 4 HP
Jolly Nature
-Stealth Rock
-Ice Shard
-Earthquake
-Superpower
I really needed some kind of hazard of my team. And Mamoswine was one of the best calls for the job. As it can be a lead as well when people are expecting your Politoed and Mamoswine can deal with a fair amount of them like Ferrothorn who's 2HKOd by Superpower. Ice Shard is priority and great espically if when something is locked into a move, or a way to get off some quick damage on a target.
What do you guys think?
