Main combos are using a Questing Adventurer, Leeroy, Gadgetzan Auctioneer or Illidan followed by a Conceal.
Other combos include using the bounce to get value for Questing and VanCleef. They are really easy to get rolling by cycling Elven Archer, or Novice Engineer so you don't lose card advantages.
Leeroy + Faceless Manipulator + Cold Blood + Conceal is a great combo as well, you can make sick burst without opponent having much counter play options.
Tinkmaster is used to clear big opponent threats like Ragnaros or using it to potentially buff your 1-2 mana minions.
Any feedback is much appreciated :>
EDIT: Bloodmage Thalnos is a great rogue card if you happen to have it. You can replace Southsea Deckhand with it.
