Use against popular Ghost types

Pokemon Damage Calculation
Mimikyu ImageMimikyu ・Jolly w/ 252 Spd. EVs: Max AirstreamMax Phantasm has 100% chance to KO
Dragapult ImageDragapult ・252 HP EVs: Max Phantasm has 100% chance to KO
Galarian Corsola ImageGalarian Corsola ・Bold with HP+Defense EVs: Max Phantasm has a 73~87.4% chance to KO

With Jolly Nature and max Speed EVs, Decidueye can move faster than Mimikyu after one Max Airstream. Max Phantasm can be used not only on Mimikyu, but also on a host of other popular Ghost-types. Even against the defensive Bold Galarian Corsola, Max Phantasm has a high chance of scoring a 1HKO.

Can also KO Tyranitar and Wash Rotom

Pokemon Damage Calculation
Tyranitar ImageTyranitar ・252 HP EVs: Leaf Blade has a 94.8~112.5% chance to KO
・252 HP EVs: Max Overgrowth will definitely KO
Wash Rotom ImageWash Rotom ・Modest w/ 252 HP EVs: Max Overgrowth has a 100% chance to KO
・Bold w/ HP+Defense EVs: Max Overgrowth has a 100% chance to KO
・Modest w/ 252 HP EVs: Max Overgrowth has a 100% chance to KO
・Bold w/ HP+Defense EVs: Max Overgrowth has a 100% chance to KO

When it's holding Expert Belt, it can definitely KO a Modest Wash Rotom w/ 252 HP EVs even with normal Leaf Blade, and has a 94.8~112.5% chance to KO Tyranitar with 252 HP EVs.
On top of that, when Dynamaxed, it can even defeat a Wash Rotom with EVs in both HP and Defense in one hit with Max Overgrowth.

Alternate Move Choices

Swords Dance Swords Dance and Shadow Sneak has a chance of taking out a Dragapult with EVs in HP.
Knock Off Can throw off an opponent's pace and strategy.

How to Use Decidueye Effectively

Spirit Shackle can stop switch-heavy opponents

Decidueye's exclusive move Spirit Shackle prevents the opponent from switching out as long as Decidueye is still out. Up against opponents who utilize strategies like the defensive loop (using multiple tanks and switching repeatedly between them), Spirit Shackle can stop them in their tracks and throw off their mojo.

Counters for Decidueye

Handle it with a type-advantaged defender

Decidueye doesn't have much in the way of a wide movepool. Up against Steel-types, it runs out of tricks up its sleeve, so sending out an advantageous Pokemon can leave it unable to act.

Best Pokemon to Use

Pokemon Description
Ferrothorn ImageFerrothorn Ranking: ★★★★★
・Can take most of its attacks with reduced damage
・Can leave Decidueye with no means of attack
Moveset & Best Build for Ferrothorn
Corviknight ImageCorviknight Ranking: ★★★★★
・Can take most of its attacks with reduced damage
・Can use recovery moves
Moveset & Best Build for Corviknight

Use a fast attacker to prevent it from acting

Decidueye has a paltry base Speed of 60, and against faster Pokemon it can fall flat. As its stats are a bit offensively focused, with a low HP and Defense, a fast Physical attacker can make quick work of it.

>>3 The typing listed is corrected but the weaknesses and resistances are still incorrect. And I believe the stat quoted is incorrect as well (Base Speed 70 not 60).
