Why run impulse in this deck when it would seem peer through depths is strictly better in a deck with nothing but instants?

What i don't get is the whole "muddle the game state" thing. I mean if i don't tell my opponent he has mana drain mana before he ends his main phase i'm a bad player and should be called cheater and pelted with vegetables? I think not. It is not MY responsibility to remind my opponent to use the mana in his pool. As soon as he changes phases i'll tell him he burnt, if it pisses him off that i didn't remind i'll probably proceed to poke fun at him the rest of the match and hope he cries. Anybody who wants to whine about their own PLAY MISTAKES should go play something else where other folks aren't involved. If i accidentally play a swords on an untargetable creature can i take it back? If i accidentally cast Yawgwill without a graveyard can i take it back? If you play the cards your responsible for knowing what they do and keeping up with it in a game situation. Simple as that, i can't figure out how it is possible to "muddle the game state" by not telling my opponent how his own cards work. I'll simply sit back, crack a smile as he pays mana for spells and tell him to burn at his combat step. If i forget to tell him to burn then it's my stupid mistake and i deserve to be beaten with a small stick and called bad names. And this concept of hinting to the opponent is even more retarded I shouldn't have to ask what mana is for, if they tap lands, they put mana in their pool. If they use it cool, if not better for me. Playing magic for a few years, losing games for misboarding, registry mess ups, missed upkeep abilities etc. Has made me pay attention to every single aspect of my game and i credit myself with it. I haven't lost a match on a technicality in a long ass time. And if a judge has the nerve to penalize me for not pointing out to my opponent something he is supposed to keep track of i'll repeatedly punch him in the throat till he turns blue.

Simply put forgetting about your own cards ability should result in mana burn. If somebody "forgets" to sacrifice to smokestack before drawing they get a game loss correct? So how is forgetting about drain mana any different? I should have to tell somebody what their cards do. If it's a question of having to aknowledge the trigger if they forget they should be penalized. Since when did magic forgive mistakes? If i accidentally play the wrong card taking it back is a loss right? So why should somebody get penalized because their opponent forgot what their own cards do? Drain decks tend to be controling and therefore hard to pilot, if you can't remember your own drain mana you should be playing simple aggro. Then again i'm an aknowledged prick. So it could just be that talking.
