Bug plays deathrites so as someone mentioned it affects on flusterstorms (they can sometimes generate the mana to pay) so I wonder if that was an issue here for you. I faced some situations against bugs that only fow helped me against discard and fluster was dead so I wonder if you had the same situations and if yes how often :)
