Who Counters Successor Taeyou in Epic Seven?

Ruele of Light, Lady of the Scales, Notos and other hard counters counter Successor Taeyou. His disruption is buff removal, not a debuff he forces through; an ally that grants buff immunity or pre-shields the enemy means his strip skill finds nothing to take and his Defense-down chance never matters.

Buff-resistant or immunity-granting supports: His disruption is buff removal, not a debuff he forces through; an ally that grants buff immunity or pre-shields the enemy means his strip skill finds nothing to take and his Defense-down chance never matters. Buff-duration manipulators and counter-dispellers: Heroes who shorten or steal buffs can rip away the attack boost and extended buffs he stacks on himself while powered up, dismantling the snowball his possession state depends on. Single-target focus and burst: He only damages one enemy at a time, so concentrated burst or focus-fire can drop him before his Fighting Spirit fills and before his 5-turn strip comes back off cooldown. Combat Readiness denial and starving his engine: Everything keys off draining enemy readiness to fuel Fighting Spirit; if there is no readiness left to steal or his own bar gets pushed back, his free turns and powered-up state stall out.

In current Champion+ RTA, Sea Phantom Politis has one of the strongest records against Successor Taeyou (64% win rate over 9,302 games).

Buff-dependent teams and stacked frontlines: His non-attacking skill dispels two buffs from every enemy at once, reliably tearing down barrier shells, defensive layers, and attack stacks that rivals lean on to function. Defensive walls and immortal/invincible tanks: Stripping their protective buffs collapses the shields and damage-prevention they rely on, and the chance to lower Defense for two turns opens those bulky targets up to follow-up damage. Fast openers trying to set the pace: His spear always crits and shaves 20% Combat Readiness off whoever he hits, denying the enemy's next turn; that stolen readiness also charges his gauge so he snowballs into bonus turns of his own. Drawn-out attrition matchups: Self attack buffs, extended buff durations while powered up, and free extra turns let him keep escalating his own tempo while peeling the enemy's advantages away every few turns.
