If thief rogue is gonna be good know is the time we have vendetta to help remove early game threats so we can get rushed down as hard also raiding part is good as it can draw our cutlass and our 3 pirates. we win in value as we cant be fatigued plus we can have a big weapon heal us every turn.  Plus who dosn't love 1 mana cards? 

Vendetta and Underbelly Fence are the key cards that will make thief rogue viable. also toggwaggle might be to much greed but hes just to fun so I can recommend him for competitive unless its a super value meta.
