Thorin, Mountain-king

The clever part of this design is that it turns the equip step itself into a trigger, not just a stat boost. Equipment in red has always leaned on combat to convert its bonuses into damage; here the attachment resolves and the equipped creature immediately fires a burst equal to its power at another creature, no attack step required. That collapses the two-part tempo cost of Equipment (deploy, then commit to combat next turn) into a single enters-the-battlefield payoff, and it rewards a board that already has a pile of Equipment waiting to be redirected. The "any number" language on the attach is what gives it reach: swap a full loadout onto the creature you want to swing, then point that inflated power at whatever needs to die. Note the flexibility of who receives the buff, too, since the enters trigger attaches to any creature you control, so the damage-dealer need not be the Mountain-king himself. Trample on a 3/4 keeps him relevant as a body once the flashy trigger has resolved, but the frame here is a Voltron-adjacent removal engine: the creature is the launch platform, the Equipment is the ammunition, and the whole apparatus resets every time you can flicker or recast him. As a dwarf noble built around the interaction between Equipment attachment and direct damage, he reads less like a beater and more like a repeatable spot-removal spell that happens to leave a body behind.
