How to beat Clan NO

Lets just say I'm not a big fan of these guys. They're pretty arrogant by being the only ones who have a uniform username system to denote their clan affiliations. They are also the only ones I've seen use force of will in a casual game. They are all about winning and they want everyone to know they are the best so I always find it my duty to break them. However, even with my best decks I keep running into trouble because there is at least always one who uses a mana-independent counterspell deck (fow, shoal, daze). Even if I created a deck with boseiju they both always run stripmine and they topdeck it each and every time. It's really frusterating, anyone got any ideas for how to break these guys?
