The Spear of Bashenga

Most Equipment sells you a stat bump and asks you to build a creature worth carrying it; this one sells you the crown first, then turns the crown into a leash. On arrival it seats you on the empty throne, and from that seat the equipped creature becomes a removal delivery system aimed at whoever tries to take the title back. The wrinkle is the trigger's timing: destruction fires when the equipped creature is declared as an attacker against the monarch, not when combat damage connects. No block stops it, no chump-sacrifice saves the tapped mana rock or spent artifact; the mere act of contesting the crown strips a tapped nonland permanent off the reigning player's board before anyone assigns damage. The +2/+2 and vigilance keep the carrier honest on the crawl back, letting it press the throne without leaving itself open to retaliation. What makes the design sing is the inversion it forces on monarch incentives. Ordinarily the crown is a card-advantage faucet its holder wants to hoard, tolerating the extra hit for the extra draw. Here the extra hit comes with a standing removal engine: hold the crown against this Equipment and you volunteer a permanent every time it swings. The card doesn't just want the crown, it wants the crown to be dangerous to hold, converting a comfortable value throne into a prize nobody can sit on safely.
