Kor Blademaster

Double strike is the most expensive keyword to hand out and the most punishing once it lands: every point of power counts twice, so a loaded weapon goes from linear to lethal in a single swing. This card anchors that math to a tribe. The 1/1 body is nearly beside the point; the real function is turning a Warrior equipment package into a first-strike-and-regular-strike engine across the board. The doubling reaches every equipped Warrior you control, not just this creature, so a wide board where multiple Warriors each carry a blade all swing twice at once. That is the payoff, and it is also where the design cost sits: each Warrior needs its own piece of equipment to qualify, since a single sword only attaches to one body at a time. The anthem gates itself twice over: it touches only Warriors, and only equipped ones. That double lock keeps a two-mana lord from trivializing the game's costliest keyword; you have to assemble the whole apparatus (a critical mass of Kor and Warrior bodies plus enough swords and axes to arm them) before the ability earns its rate. It belongs to a small lineage of white equipment-tribe payoffs where the gear is the deck and the creatures are delivery vehicles, and it multiplies combat output rather than merely adding to it: the distinction between an anthem that stacks power and one that doubles what your weapons already provide.
