Who Counters Yuna in Epic Seven?

Empyrean Ilynav, Swift Flagbearer Sigret, Setsuka and other hard counters counter Yuna. Her value leans on the team-wide Attack buff; an enemy that steals it not only removes her offense boost but hands that Attack to the opposing side, flipping her support against her.

Buff stealers: Her value leans on the team-wide Attack buff; an enemy that steals it not only removes her offense boost but hands that Attack to the opposing side, flipping her support against her. Buff stripping and dispel: Dispelling her Attack buff erases the payoff of her second skill, which sits on a 5-turn cooldown, so once it's gone she can't quickly restore the team's damage. Buff-duration reduction: Cutting the duration of her 3-turn Attack buff shortens her offensive window and forces her back onto the long cooldown sooner, blunting the team's burst. Out-speeding her and bursting first: Her whole game plan is moving first to open and accelerate; a faster team that strikes before she acts denies her the turn-meter snowball, and she has no passive or self-protection to fall back on if focused.

Slower teams she can outpace and chip down: High base speed plus her own 15% turn-meter push means she usually moves first, and her drone hits the whole enemy line at once, so opponents who don't outspeed her eat AoE damage before they act. Shrinking or small enemy lineups: Her cannon deals more damage the fewer enemies are left (three or fewer), so as a fight thins out she becomes a much harder hitter, punishing teams already down a member. Allies that snowball off speed and Attack: She is a force multiplier: the team-wide Attack buff for 3 turns, the 5% turn-meter push to all allies, and her own extra turn stack up to give a damage-focused team faster, harder rotations. Enemies with no cleanse against opening pressure: As a fast AoE opener she stacks early damage across the board, so teams that can't immediately reset or heal through her first volley fall behind on the very first rotation.
