If your friends are losing this badly... no offense but you need to find a a better play group. There is NO reason that a 3+ person pod should be losing to the same deck over and over. Regardless of cost, cards they own, money spent. It sounds like they need to learn to play magic.
the question you should be asking it why not uril?
In my own experience, because I've obliterated every uril deck i've faced with my pocket-change bruna deck, even when making strategic mistakes that would normally be game-ending. If that makes my opinion inherently short-sighted, then so be it.
Perhaps when I beat a deck worth 12-15 times more than my own played by players FAR more experienced/better than me I start to doubt the commander it is built around, because I'm nowhere near as good as them or even consider myself an intermediate player by any means. Maybe I've just been tainted by that experience.
