Resolute Strike

Equipping is normally a sorcery-speed action, and that timing wall is what elevates this above a small combat trick. The pump line lands on any creature and keeps the card castable when the board isn't cooperating, but the second clause is the design: it lets a Warrior grab a piece of Equipment mid-combat, after attackers and blockers are already declared, for no extra mana. That is a maneuver most decks physically cannot execute. Moving a sword onto a freshly declared blocker, or sliding an evasion-granter onto a Warrior that's about to connect, happens at instant speed here and costs nothing beyond the single white mana you were already spending. The conditional folds two distinct effects into one spell: a raw boost that works everywhere, and a free reattach that fires only when a Warrior is on the receiving end. When the condition is met on resolution, the equip clause turns a fine trick into a genuine blowout, because the opponent has already committed to a combat math that assumed the Equipment stayed put. This is tribal glue that pays out only inside the archetype built to satisfy its condition, which is precisely the shape a one-cost common should take: floor-playable as a bare pump, ceiling-defining when the Warrior and the Equipment both show up.
