Here's the Situation...

You're playing Lilith, or whoever you feel like imagining yourself as right now [[lol doesn't matter]] but lets say your not used to using, or going against the Peacekeeper and your Opponent Sonnia Criid is now running the Big Spider thing. You go through the game not really worrying about anything and then you realize

oh crap! the Peacekeeper has those faulty wires!
Then you realize, there were several events at which he flipped a 4 or lower.

now here's the question... I know it comes down to sportsmanship, but who's responsibility is it to remember/inform your opponent of the more subtle of rules like the Peacekeeper, or Rami LaCroix who if he flips a one can't cheat fate.

honestly can you let the competitive spirit let simple rules like that slide here and there but then call it on them? I don't know about you but honestly there are alot of double edged rules here and there that makes me feel almost obligated to have the book open to the opponents models just incase something backfires ya know?
