I have used it as exactly that, a super Monarch, in politics decks. However you have to be pretty darn brave because it's just a bit too good - I'm aiming to make people fight over it, but in doing so potentially drawing them a bunch more cards, and if someone can hold onto it it's a pretty big mana rock.
Probably the more normal but more boring way is just to pillow fort the heck up. This actually isn't that hard if you're building around it, but it won't just slot into any old dexk.
