Keeper of Keys
Most creatures that make you monarch treat the crown as a lure: they hand you the extra card and the incentive to attack, then dare the table to hit you and take the title back. This one weaponizes the position instead of dangling it. Installing you as monarch on entry is only the setup; the payoff arrives on your following upkeep, when every creature you control becomes flatly unblockable for the turn. Not evasion against ground blockers, not menace, just unblockable, so long as the crown is still on your head. That last condition is the whole balancing act. The grant is gated behind holding the title and fires only once per turn, which means the instant an opponent connects and steals the monarchy on their turn, the engine goes dark until you take it back. Without that leash, this would be a permanent global keyword, and the design refuses to hand out that much for free. The result is a self-reinforcing loop: monarchy pushes you to attack, the attacks land untouched, and the unanswered damage stacks fast enough that assembling a counterattack to dethrone you becomes its own problem, since your board is meanwhile walking through unopposed. It reframes the crown from a fragile bonus you defend into a one-sided clock you press, turning the title into an offensive engine for exactly as long as you can keep it.
