Hero's Heirloom

Equipment that reads differently depending on who is holding it, and the split is deliberate. Bolted onto a rank-and-file creature, it is a plain +2/+1: a serviceable but unremarkable stat bump for two mana that would never earn a slot on its own. Give it to a legend, and the same two-mana artifact hands over trample and haste, turning a summoned hero into an immediate threat that punches through chump blockers and connects the turn it lands. The design is a payoff piece dressed as a generic combat aid, rewarding a board built around named characters without demanding they be built around this specific card. The haste rider is the load-bearing clause: it collapses the usual sorcery-speed vulnerability of a fresh, expensive creature by letting it attack the turn it arrives, and the trample ensures that pumped body cannot be walled by a single blocker. It is a small, honest engine for legendary-matters strategies, the kind of equipment that stays inert in the wrong list and quietly overperforms in the right one, all without ever asking for more than four total mana to suit up.
