Yukari Yakumo
Type:
HP: 112
Atk: 79
Def: 88
SAtk: 220
SDef: 160
Spd: 61
Ability: Filter / Wonder Skin / Regenerator
Tier: Fundex Uber
Yukari has both a very high Special Attack stat and a great Special movepool to use it with. She gets a boatload of Other moves as well. And on top of that, she has a great ability known as Regenerator. She might not have that much Speed, but she can overcome that with either a Choice Scarf or Agility. Also, most defensive Fundex Ubers have terrible Speed even compared to Yukari, for example Weegee with his base Speed of 2.
"Trip to the Old Station"
Yukari Yakumo (F) @ Life Orb
Ability: Regenerator
EVs: 52 Def / 252 SAtk / 204 Spd
Modest Nature (+SAtk, -Atk)
- Agility
- Psychic / Train Wreck
- Focus Blast / Hidden Power [Fighting]
- Dark Pulse / Shadow Ball
After having used Agility, with the given Speed EVs, Yukari reaches enough Speed to outspeed a max Speed Sariel. Psychic is your STAB attack, and Focus Blast / Hidden Power and Dark Pulse / Shadow Ball provide coverage against those who resist it or are called Giygas. Train Wreck can be used over Psychic because it has more than double the power, but it forces Yukari to laze around for one turn.
"Creation and Destruction"
Yukari Yakumo (F) @ Leftovers
Ability: Regenerator
EVs: 252 HP / 252 Def / 4 SAtk
Bold Nature (+Def, -Atk)
- Calm Mind
- Psychic / Stored Power
- Focus Blast / Hidden Power [Fighting]
- Dark Pulse / Shadow Ball
Instead of speeding her up, this set makes Yukari a stone wall so she can attack without getting knocked out first. The EV spread grants her the highest possible Physical defense, while she boosts her Special Defense with Calm Mind, together with Special Attack to dent the enemy team. Regenerator might sound silly as an ability while you won't be switching out anyway, but it's useful in case of a failure or Taunt while you're boosting. Stored Power is a good option over Psychic, because two Calm Mind boosts will already have made it more powerful than Psychic.
"Youkai of Eyed Gaps"
Yukari Yakumo (F) @ Leftovers
Ability: Regenerator
EVs: 252 HP / 4 Def / 252 SDef
Calm Nature (+Def, -Atk)
- Psychic
- Will-O-Wisp
- Taunt
- Recover
This set focuses on Yukari's great Special defensive stats, which are 112 and 160 base. Train Wreck should not be used here, as the recharge will hinder the walling. Will-o-Wisp takes care of Psychical sweepers who would otherwise hit this set's major weak point. Taunt stops any of Swad's setup attempts and other walls too. Recover is a great move for the last slot to make Yukari last out longer, together with Regenerator. EVs are given for maximum Special walling.
"Quadruple Barrier"
Yukari Yakumo (F) @ Light Clay
Ability: Regenerator
EVs: 252 HP / 252 Def / 4 SDef
Bold Nature (+Def, -Atk)
- Reflect
- Light Screen
- Taunt
- Psychic
Reflect and Light Screen don't just improve Yukari's defenses, but support your entire team for eight turns too. The EVs makes sure Yukari can take Physical attacks as well, as there is no room for Will-o-Wisp on this set.
Other Options
Dragon Pulse, Draco Meteor, Fire Blast, Flamethrower, Ice Beam, Overheat, Scald, Signal Beam, Vacuum Wave, Volt Switch, Nasty Plot, Thunder Wave, Trick
All moves besides the latter three are moves of the many Special attacks Yukari has that are useful, for each their own use. Scald, for example, has the useful side effect of burning and is super effective on Malleo, Dragon Pulse is super effective on Pearl and Vacuum Wave has priority.
Nasty Plot greatly boosts Yukari's already awesome Special Attack, but she often isn't fast enough to make good use of it.
Thunder Wave is another move that can help Yukari outspeeding the enemy team.
Trick can screw up walls when used together with Choice items, without having to Taunt.
Checks and Counters
Essej will be faster than Yukari whatsoever (unless she managed to get multiple Agility boosts) and has a super effective STAB Crunch. DanZalgo knows Nasty Plot and will damage Yukari a lot using Corrupt, even if she has Calm Mind. Maribel-B walls Yukari very well and hits back with her signature Berserk. Giygas walls any of her sets that lack Dark Pulse or Shadow Ball.
