This is an awkward card for rogues to use and they aren't the class that likes going wide. They have 2 mana 2\2 + 2\1 and it sees no play. This one is no much better. 2\2 is too easy to kill. It is similar to that 0\3 totem that gives 1\1 murlocs unconditionally every turn in a class that loves going wide.
It may be OK in even rogue, but even rogue is a fringe deck that needs much more support. Odd rogue can't play this by definition Tempo rogue. You do what? Play this on 2 hoping to go dagger 1 drop next turn? It will just get killed by other tempo decks and control can ignore it for few turns before wiping it together with all that tokens few turn later.
Deathrattle\miracle rogues have different game plansSome kind of pirate rogue? Well we haven't seen other pirates of the set. Maybe some deck of this type will emerge but I doubt that it'll be stronger than odd rogue.
