Talonflame with Atk/Spe EVs attacking with ability+item-boosted Flying moves. Gale Wings activates at full HP, Priority-boosted high-power Brave Bird strikes first is possible.

Alternative Move Options

Dual Wingbeat to avoid recoil

Brave Bird's recoil limits Gale Wings to one use. Dual Wingbeat has lower accuracy/power but no recoil, so Without opponent damage, priority +1 can be repeated.Pick by preference.

Jolly AS Attacker Role

With base 126 Speed, Taunt/Will-O-Wisp restrict opponent status/physicals. Ability stops when HP drops, but High Speed disrupts opponent setups while pressuring — functions as an attacker.

Threats

Weak to Sandstorm and Stealth Rock

Talonflame is 4x weak to Rock, so Stealth Rockdeals 1/2 max HP damage. Also Sandstorm HP gets chipped and ability stops working — be careful.

Max Atk/Spe with team-support moves and Focus Sash action-guarantee — doubles support/attacker. At full HP, Flying moves get priority, boost ally Speed before opponent acts — viable.

Alternative Move Options

Will-O-Wisp as support option

Swap Taunt for Will-O-Wisp to disrupt physical attackers.

Dual Wingbeat also viable for Flying

Brave Bird slot can be Dual Wingbeat. Power drops but no recoil — easier. Also, can OHKO Sash Whimsicott from above — strong point.

Doubles Support Role

Support moves blocking opponent priority protect allies while it joins offense with high-power Flying as lead. Item lets it tank one hit, manipulate board for ally-friendly play — specialty.

Threats

Unfavorable vs. Rock

Rock halves Brave Bird and hits 4x weakness with Rock Slide etc. Especially Tyranitar/Hisuian Arcanine OHKO unless Attack is lowered, so don't force stays — consider switching.
