I climbed from rank 500 all the way up to rank 18 so far this week (8000sp-9128sp) using mostly Negative and Sandman. Really consistent decks in this meta. Negative mostly loses to alioth, getting clogged, or bad draws (leave for 1 cube). Snap early when you have psy/rav + neg in hand since you are usually winning with early negative. Sandman is just playing out as much tempo and moveable cards (jeff/nocturne) and then sandman into usually ultron but sometimes Red Hulk or Klaw. Jeff+Copycat just gives insane information on your opponent an their deck/potential output. Can put that combo into a bunch of decks.
