Regal Behemoth

Most crown payoffs reward you for surviving to your end step with the title intact, drawing an extra card once per turn; this one cashes in the moment your lands tap, adding an additional mana of any color for every land you tap for as long as you keep the throne. That reroutes the whole subgame. The monarch is usually a card-advantage clock; here it becomes a ramp-and-fix engine, five tapped lands funding ten mana across colors, a green base underwriting an aggressive splash off nothing but basics. Six mana buys a 5/5 trampler that hands you the crown on the way in, so the body already puts you a turn ahead in the monarch's draw race. But the mana doubling is where it earns the slot. The catch is structural rather than printed: the crown can be taken in combat, and the instant an opponent connects, your lands snap back to ordinary output. The card asks you to defend the title, which trample helps you do on the attack and nothing at all on the block. It is a payoff that doubles as a target, lavish while you hold it and inert the turn you lose it, and that volatility is the entire bargain.
