The Wandering Emperor
Flash on a planeswalker reads like a contradiction until the second line resolves it: her loyalty abilities are instant-speed only on the turn she enters, and that single-turn window is the entire design. She lands during the opponent's attack step, exiles a tapped attacker with the minus-2 and gains two life, functioning as removal that happens to leave a permanent behind. She lands at the end of the opponent's turn to make a vigilant Samurai with the minus-1, a blocker ready before your next draw. Or she lands and ticks up with the plus-1, dropping a first-striking counter onto a creature already in combat to steal a trade the attacker expected to win. The card answers the oldest structural weakness of the planeswalker template: a fresh walker sits exposed for a full turn cycle before its controller can protect it. Here the defense and the tempo are one action, because whatever ability you activate is also the reason the attack you feared no longer lands, or lands into a body that trades. Every mode is defensively live, so there is no dead activation and no wrong turn to hold her for. She reads as a modest three-loyalty midrange walker on paper; the instant-speed clause is what makes her an answer that dictates when the tempo swings, without asking you to tap out or commit anything on your own turn.
