WaterHP: 140

Spd: 95
SpAtk:100
SpDef:55
Abilities: Natural cure/Synchronize
Why, dear god why, is this not on standard suspects? With a rockin physical body of 140/90 and an insane
95 speed H Eirin is an absolute monster stat wise with fantastic defensive and offensive typing and the movepool to back it all up. Oh and she has natural cure, but seriously, 95 speed, on a wall with 100 special attack.
Recommended set: (So many bad names I could give this, just make one up)
(No you dont get to look at Eirin again)
The Only SetHelper Eirin @ Leftovers
Ability: Natural Cure
EV's:Def 252/ Spd 236/ SpAtk 22
Nature: Bold (+Def/-Atk)
-Aqua Shower/Hydro Pump
-Poison Bomb/Mana burst/Toxic/Hypnosis
-Recover
-Burn Powder
Usage: Attack Suwako is THREAT to so many things, Tailwinders are often running lum to avoid annoying burn. Sub CM flat out sets up on slower walls. Ya, fuck that noise, H Erin out speeds 90 base fully invested with no plus speed nature as well as +Speed base speed 80 puppets with the given EV's. H Erin can then proceed to OHKO anything weak to aqua shower/Hydro pump or simply burn stall them out with her Yoshika level physical bulk. Swapping her in is pretty damn easy given her messload of resistances (6 in total) and neutral hits. P bomb covers the ever annoying star forms and D Kayuga, mana burst hits Sara who can otherwise set up on poor Eirins face with her own crazy bulk (Inb4fanfic) and Hypnosis wrecks havoc on the special attackers your opponent will be sending in to pick on that terrible spec def stat.
Support:A combination of H Eirin/Bulky Nature/Steel is amazing when given the right team mates since literally anything not covered by your core can be covered by a typing that gives immunity (Steel/earth/flying) or an ability (levitate, flash fire, volt absorb) and can be fast attacked or set up on. T Aya gets big props here as she can both twister and loves wish heals cause brave bird everything.
Counters: Namazu takes absolutely nothing from any of HEirins moves and can 2 hit Ko with ease via discharge. Past Fishy its a good idea to hit HEirin on her weaker spdef stat, 55 special Def its the price H Eirin pays for her otherwise amazing stat spread and with weaknesses to the common earth and reason types alongside a less used wind vulnerability she's forced out by just about any strong special attacker faster than her on the revenge kill. She also hates spikes. Hard counters to HEirin are highly dependent on her second attacking move, Seiga, Sariel, (T)Byakuren, and the Shikieki forms can all come in on Poison Bomb HEirin and force her out with ease however they really do not enjoy taking mana bursts. On the other hand (D)Kayuga, DDaiyousie, A Patchy and the Star Saphire forms can easily take on Mana Burst HEririn, P bomb can completely ruin them though.
Options: With a swimsuit (inb4fanart) and timid+max speed spec attack Eirin also makes a fearsome bulky attacker. Just in case you want to mix things up.
