probably tempo rogue. it's strong across the board and it's not too difficult to pilot.
carpet zoo-lock is good as well though IMO, and cheaper to build.
also if you wanted more than one deck, you can't go wrong with bomb hunter as this is good against control decks. if you were to build say tempo rogue or zoo and bomb hunter, you'd have a nice range so you can switch decks if you hit a certain meta pocket.
