To me, there's no such thing as a deck that's too pretty to use. It's the purpose behind its creation. I'm not one of those collectors who buys by the brick only to let decks collect dust on a shelf, never opened. It's like buying a famous work of art and never unpacking it, instead admiring the crate that it came in.
I've had an interesting change-of-mind about one deck in particular, the Monarchs. When they first came out, T11 was hyping them to no end, making them sound better than all of the world's deities on one stage with Jimi Hendrix at Woodstock. I was complaining about them as loudly as anyone else. But after the hype died down, I looked a little closer at them and realized they're actually a well-done design - unique but familiar, and very attractive and eye-catching without having to bash you over the head with it. Monarchs and Silver Monarchs are now among my go-to decks. And to their benefit, T11 learned that the hype machine need not be turned to 11 in order to generate interest in a deck - they've never hyped another deck like that since.
And yes, you're getting "guff" about your deck's name, Mallanaga, because if you borrow from a popular copyrighted work like you are, it's only a matter of time before the lawyers fly over and carpet-bomb you with C-and-D letters... Believe it or not, we're giving you that advice for your own good because we've seen other projects crash and burn in similar fashion, some in the early stages (the "Heroes of Steampunk" deck, which you can't even find in a KS search any longer due to a C&D from Lego because all the art was made using modified Lego figures without the company's permission), some much later down the road (the "Bicycle Army Men" deck didn't get crushed by people speaking Legalese until after the campaign was successfully completed). Even if you can find a public domain work that predates G.R.R. Martin's books and contains the term "Westeros", you may still have to hire a lawyer if his lawyers decide to pursue you anyway, just to defend yourself in court. It simply isn't worth the hassle and the expense just to get publicity for your deck.
