Staunch Throneguard

A crown-granter needs a body that can keep the crown, and this construct is built to nothing else. The monarch title travels to whoever lands combat damage on its current holder, which makes any card that hands you the crown quietly responsible for defending it too: a fragile granter is a gift-wrapped bounty for the table. A 2/5 answers that problem directly. Five toughness turns aside the incidental swings that would otherwise steal the title on an opponent's turn, and vigilance lets the body sit back on defense while still tapping out to reclaim the crown if someone else has taken it. The stat line is doing all the design work here; there is no lifegain, no card draw, no second trigger stapled on to sweeten the deal. You get one instance of the monarch and a wall stubborn enough to protect it, priced for exactly that and nothing more. It is worth appreciating how narrow the brief is: the monarch is only an advantage if you can hold it turn after turn, so a granter this plain lives or dies on whether its body can survive contact. This one is engineered to survive contact, and that discipline is the entire pitch. Where flashier monarch enablers try to bundle the crown with other value, this one strips the effect to its structural minimum: hand over the title, then stand in the way of anyone trying to take it back.
