What are the different types of rogue decks out there, and how does rogue do in casual play. I'm at 2-star gold and have been forever, so I'm probably just perma-stuck there (I made the mistake of leveling a lot of my decks to 10 while in ranked mode -oops- and lost a whole lot, so I'm at over 175 wins and still 2 star gold). Unless they reset MMR or rankings I'm not going to bother trying to recover from that.
Here are the expert cards I have:
Cold Blood x2
Blade Flurry x1
Defias Ringleader x2
Perdition's Blade x2
SI:7 Agent x2
Any of those that can be safely DE'd/just don't measure up? Are there any I don't have that I should make a priority? I have a lot of other cards I can DE from my druid deck that I've given up on. Any neutral cards that just really synergize well with a rogue deck? I have some ideas about all of these things, but I'm looking for some confirmation before I doing something that isn't undoable.
Thanks in advance!
Edit: I've also been playing with the pirate cards and have several of those. Any other themes that work well?
