Does well vs. Reno, control, midrange, big, and combo decks (if you can mill and burn their combo pieces). I have played this to low diamond and beaten every non aggro meta deck with it at least once. 

unlikely to get past diamond, mill Rogue gets wrecked by any aggro. Quicker to just concede in these matchups and move on.
