One of Decidueye's biggest drawbacks is its awkward speed tier: it's too slow to be a sweeper but not slow enough to abuse Trick Room. So, this set utilizes a Choice Scarf to patch up Decidueye's Speed, enabling a Jolly Decidueye to outspeed and revenge kill threats such as Salazzle, Zygarde 10%, and Lycanroc-Dusk and is one point away from speed-tying with Aerodactyl. An Adamant one, on the other hand, can hit incredibly hard and still outspeed Virizion and non-scarfed Moltres and Tyrantrum.
The set is pretty simple to use: it comes on weakened threats and revenge kill them. Spirit Shackle is your main STAB and comes with the great effect of trapping your opponent. Leaf Blade is your second STAB and has a nice chance to critical hit. Brave Bird is primarily there to hit Fighting-types like Virizion, Bewear, Machamp, and Pangoro. U-turn is the last move on the set, allowing Decidueye to escape from unfavorable matchups such as Mandibuzz.
Overgrow is your ability of choice, allowing Decidueye to fire off powerful Leaf Blades when it's at 1/3rd of its health. Long Reach could be used instead if you
really want to bypass Rocky Helmet and Bewear's Fluffy ability, but 9 times out of 10 Overgrow is the better ability.
