Nahiri, Storm of Stone

The static abilities are the whole design here, and they point toward a role most planeswalkers never fill: this is a walker built to run an equipment deck rather than to grind card advantage from behind a wall of blockers. Handing your team first strike during your turn while dropping the cost of every equip activation turns a board of otherwise fragile creatures into a swarm that wins combat before the opponent's blockers can trade back, and the equip discount lets a swords-heavy hand suit up two or three attackers in a single turn. The minus ability confirms what kind of walker this is: it only burns tapped creatures, so it cleans up whatever survived combat or picks off a would-be attacker the turn after it swings, but it cannot answer an untapped blocker sitting in the way. That constraint is deliberate. Nahiri does not defend a stalled board; she rewards a deck already applying pressure, and the loyalty starts high enough to weather a few points of retaliation while the static engine does its work. The hybrid mana in the cost keeps the door open to a mono-red or mono-white build while the split identity signals where she belongs: aggressive equipment strategies that care more about connecting than about the individual bodies doing the connecting.
