[SET COMMENTS]
* With a Choice Item, Chi-Yu can choose to become either a spicy revenge killer or a scorching wallbreaker!
* **Flamethrower versus Lava Plume**: Flamethrower's higher power makes it the better cleaning tool, but Lava Plume's higher burn chance gives Chi-Yu a good shot of punishing major physical attacking fores such as Dragonite, Azumarill, and Garchomp that resist Fire.
* **Psychic**: This is Chi-Yu's most powerful attack against Iron Moth and Toxapex and can pick off weakened Annihilape without Overheat's Special Attack drop.
* **Tera Blast**: Even before Terastallizing, Tera Blast is a decent coverage move that hits Azumarill and Roaring Moon.
* **Memento**: Memento is a great filler move on Choice Scarf Chi-Yu, especially for setting up dangerous sweepers like Chien-Pao and Dragonite.
* **Sleep Talk**: Sleep Talk makes Chi-Yu a decent Spore absorber against Amoonguss and Brute Bonnet and even against Breloom with a bulkier EV spread or the correct Tera type.
* **Modest versus Timid**: Modest is generally preferred since Chi-Yu's Speed isn't too impressive, but Timid does ensure that Chi-Yu outspeeds Annihilape and Mimikyu, who are fully capable of revenge killing Chi-Yu that lack Choice Scarf.
Other Options
========
* **Fire Blast**: Fire Blast's shaky accuracy can be an issue, but it's a far better sweeping tool than Overheat.
Tera Types
=========
* *Tera Dependency - Low**: Chi-Yu's damage output is red hot even without Terastallization, making it a fairly flexible Pokemon.
* **Fire**: Tera Fire Overheat is extremely difficult to wall without a resistance, making it an easy choice for Chi-Yu. It also lets Tera Blast become a powerful STAB move while Chi-Yu is locked into using it, letting it get around the normal limitations of using a Choice Item.
* **Fairy**: Tera Fairy is Chi-Yu's best shot of defeating Roaring Moon and Hydreigon and gives it an important Fighting-type resistance.
* **Grass**: Tera Grass is a good response to Azumarill and Palafin-H and lets Chi-Yu avoid being OHKOed by Iron Bundle's Hydro Pump.
* **Dark**: While Tera Dark is nowhere near as impressive as a boosted Overheat, Dark Pulse has excellent coverage and also removes Chi-Yu's troublesome Stealth Rock weakness.
* **Water**: Getting a Water-type resistance is always useful, but the real key for Tera Water is that it helps Chi-Yu in the mirror match-up, especially against Assault Vest Chi-Yu.
* **Ghost**: Tera Ghost lets Chi-Yu surprise Extreme Speed Dragonite and Mach Punch Breloom.
Items
========
* **Choice Scarf**: Choice Scarf patches up Chi-Yu's lukewarm Speed into something usable for revenge killing and also makes bulkier builds easier to use.
* **Choice Specs**: Choice Specs trades revenge killing for terrifying wallbreaking power. With Tera Fire, the heat gets so extreme that even Blissey is 2HKOed by Overheat!
Bulkier EV Spreads
========
* **228 HP / 12 Def / 124 SpA / 4 SpD / 140 Spe with Modest**: This is a bulky spread meant for Choice Scarf, outspeeding up to Iron Bundle. The bulk investment survives Breloom's Mach Punch, Mimikyu's Play Rough followed by Shadow Sneak, and has a good shot of surviving Tera Normal Choice Band Dragonite's Extreme Speed. 40 EVs can be moved from Special Attack to Speed to outspeed Dragapult at a serious cost to power.
[SET]

Ability: Beads of Ruin
Level: 50
Tera Type: Fire / Water / Fairy
Modest / Timid Nature

- Overheat / Flame Charge
- Flame Charge / Psychic / Tera Blast
[SET COMMENTS]
* Chi-Yu's sizzling offensive power lets it get away with a wide variety of options that wouldn't fit on a Choice item set.
* **Flamethrower versus Lava Plume**: Flamethrower's greater power makes it the better option in most instances, but Lava Plume's higher burn rate is good at punishing switch-ins like Azumarill and Dragonite.
* **Flame Charge**: Chi-Yu is powerful enough that even without an offensive item, getting a Speed boost makes cleaning teams late game very achievable.
* **Psychic**: Psychic is Chi-Yu's best option against Iron Moth and Toxapex. Note that Overheat will out-damage targets like Annihilape though.
Other Options
==========
* **Will-O-Wisp**: If not using Assault Vest, Will-O-Wisp severely punishes bulky physical threats like Azumarill and Dragonite that may switch in and works great with Terastallization to surprise other bulky threats such Ting-Lu.
Tera Types
========
* **Tera Dependency - Medium**: Chi-Yu has a ton of weaknesses to common attacking types, so while Terastallization isn't needed to function, it can especially help bulkier Chi-Yu check more threats and otherwise focus less on hit-and-run attacking.
* **Fire**: Beyond giving Overheat soul-melting damage output, Tera Fire gives Chi-Yu a vital Fairy-type resistance against Flutter Mane and a good shot of OHKOing even bulky Flutter Mane with Overheat.
* **Water**: Tera Water works great on Assault Vest Chi-Yu with Tera Blast, ironically turning it into a decent check against other Chi-Yu! It also eases the matchup against Palafin-H.
* **Fairy**: Tera Fairy has good synergy with Chi-Yu's former typing, giving it a vital Fighting-type resistance and ensuring Chi-Yu is not walled by Roaring Moon.
* **Grass**: Tera Grass is a huge help against Azumarill and Palafin-H and lets Chi-Yu more safely set up Flame Charge against Spore users like Breloom and Brute Bonnet.
* **Ghost**: Tera Ghost is Chi-Yu's best hope against Dragonite's Extreme Speed and Breloom's Mach Punch.
Items
========
* **Assault Vest**: Chi-Yu has shockingly decent Special Defense, so Assault Vest lets it preform much better against Flutter Mane and opposing Chi-Yu.
* **Life Orb**: Life Orb lets you get away with playing this set far more offensively at the cost of being even weaker to priority attacks than usual.
* **Focus Sash**: If using a more offensive spread, Focus Sash can be worth it to flip the tables on fast offensive foes such as Iron Bundle.
* **Eject Pack**: This turns Overheat into a one-use pivot move, surprising foes with a momentum shift in your favor.
EVs
========
* **228 HP / 12 Def / 124 SpA / 4 SpD / 140 Spe with Modest**: This bulky spread is perfect for Assault Vest and Flame Charge, letting Chi-Yu outspeed Iron Bundle after a boost and avoid a OHKO from Breloom's Mach Punch. It also avoids a KO from Mimikyu's Shadow Sneak following Play Rough and often survives Tera Normal Dragonite's Choice Band Extreme Speed. If outspeeding Dragapult after Flame Charge is a priority, 40 Special Attack EVs can be moved to Speed.
* **4 HP / 252 SpA / 252 Spe with Modest or Timid**: When using more offensive items like Life Orb or Focus Sash, going a more offensive route makes Chi-Yu a better late-game sweeper. Modest is preferred for the damage output, but Timid outspeeds Annihilape and Mimikyu.
[SET]
Nasty Plot (Chi-Yu) @ Focus Sash / Life Orb
Ability: Beads of Ruin
Level: 50
Tera Type: Fire / Fairy / Grass
Timid / Modest Nature
EVs: 4 HP / 252 SpA / 252 Spe
IVs: 0 Atk
- Nasty Plot
- Flamethrower
- Dark Pulse
- Overheat / Tera Blast / Substitute
[SET COMMENTS]
* While not easy to sweep with due to it's Speed, Chi-Yu becomes a a hot wallbreaker after setting up Nasty Plot!
* **Overheat**: Overheat's Special Attack drop may conflict with Nasty Plot, but it'll deep-fry almost any Pokemon slower than Chi-Yu, making it a worthy wallbreaking tool.
* **Substitute**: Substitute does a great job of punishing common status users such as Wo-Chien, Amoonguss, and Toxapex. If Terastallized, Chi-Yu has a good chance of retaining its Substitute against Salt Cure as well.
* **Flame Charge**: While setting up both Nasty Plot and Flame Charge is unlikely, it does give Chi-Yu a different avenue to sweep late-game.
* **Timid versus Modest**: While this Chi-Yu is more focused on extreme wall-frying than sweeping, Timid is nice for outspeeding Annihilape, who certainly can't handle boosted attacks well.
Tera Types
=========
* **Tera Dependency - Medium**: Chi-Yu's poor defensive typing can make it fairly easy to revenge kill, so having Terastallization free gives Chi-Yu much more KO opportunities beyond cooking slower threats.
* **Fire**: Tera Fire makes Overheat an insane wall-breaking move, with Life Orb threatening to OHKO Blissey after a boost!
* **Grass**: With Tera Grass, Chi-Yu can threaten to OHKO Azumarill after a boost in addition to avoiding a OHKO from Aqua Jet and Jet Punch.
* **Fairy**: Tera Fairy gives Chi-Yu a helpful Fighting-type resistance and a better match-up against powerful Dragon-types like Dragonite and Roaring Moon.
* **Ghost**: Tera Ghost covers Chi-Yu's Fighting-type weakness and helps against Extreme Speed, making it much harder to stop its sweep.
* **Dark**: With Nasty Plot and Life Orb, Tera Dark Chi-Yu is capable of OHKOing even the most specially defensive Annihilape with Dark Pulse!
* **Water**: Tera Water lets Chi-Yu deal with opposing Chi-Yu more comfortably and punish the common Tera Fire Annihilape with Tera Blast.
Items
========
* **Focus Sash**: Focus Sash makes setting up Nasty Plot much easier, at the cost of power.
* **Life Orb**: While it makes Chi-Yu even more vulnerable to priority moves, Life Orb is otherwise an excellent wallbreaking item, notably giving Chi-Yu a better matchup against Annihilape.
Alternate EV Spreads
========
* **24 HP / 12 Def / 220 SpA / 252 Spe with Timid or Modest**: If using Substitute, this spread prevents Garganacl with 4 Attack EVs from breaking a Terastallized Chi-Yu's Substitute with Salt Cure. Note that Body Press and Earthquake will still break the Substitute unless using the correct Tera Type.
