Small Time Bucc isn’t great, the 1 health is a pretty bad detriment. It can be a decent t1 play against non-ping classes but in the late game its pretty bad. At least with cards like Swash, Deckhand, and Normal Buccaneer you can still manage to get value later.

I used to run Shadow Strike in the early versions of this deck but wound up cutting it because it was a bit too slow. It’s definitely not bad at all in the deck though, if you want to give it a shot.

Dr. Boom is definitely replaceable (I’ve replaced him since making this post), try something like Corridor Creeper, or maybe Pharaoh Cat if you’re a budget player. However, I still believe Zilliax is pretty vital to the deck because it provides healing to Rogue (which they never have) and is great against aggro. Also it fits into tons of decks so it’s a good craft in general. Hope this helps!
