Clan boss is entity of its own and is not member of any faction, much like all other dungeon bosses. So tough luck with his passive. But overall, a great champion, wouldnt be bad to have him even without that passive in CB fight.
But be ready to be disappointed unless you hoarded quite a bit of shards. x10 are usually for something very specific you want and quite less rewarding than x2 in terms of chances.
