Early Pool 3 - Obliterate or Retreat Deck

I'm in early pool 3 and I got Mister Negative so I made this deck with what I had. Turns out it's not that bad. 
So i literaly never snap with this deck ,because you usually play only one or two cards before turn 4,and opponents usually snap by then. If by turn 4 I've drawn Mister Negative and Magik I just play it out for 4 cubes ,because the last two turns is when you dump all low cost cards on the board ,wich people dont usually counter well ,so you win. If I don't draw those two ,usuallyJubilee pulls them out ,wichever one I need. I'm actually surprised how wellJubilee works here.

If I haven't played any of those by turn 5 ,just retreat. So you either lose 1 cube or win 4 with this deck. Also don't snap on turns 6 or 7 because they'll just leave and you get less cubes ,the trick is to make them think they're winning right up until the end.

White Tiger  and Iron Man are crazy when they get hit by Mister Negative and Bishop  and Ironheart  are great anyways ,but Bishop can be 0 cost 3 power on turn 7,ideally and you can get it up to 6 or 7 power in that same turn after dumping all of the cards.

Also, Morph  is great too ,either as a turn 3 play ,wich sometimes sucks ,but sometimes hits those big cards that just make people retreat ,I've rarely had Morph  make it worse for me ,honestly. Even if its something mediocre it's still ok for us. But Morph  can actually be insane on last turn ,when it costs 0, hitting those unplayed The Infinaut  giving you huge and unexpected power swings.

Sunspot is great when drawn early ,cause you have some unspent energy pretty much every turn.

As I said ,I'm early in pool 3 ,so I don't have a lot of the cards yet ,but honestly i would just swap The Punisher  for Psylocke  when I get her and maybe Blue Marvel  for Black Panther  wich I also don't have. Everything else I think works. 

If anyone tries this ,leave a comment on how did this work for you.
