Thanks for the replies! I have some more questions about this:
When planning your strategy: cursers > money > good trashing > +card > +buy > bad trashing > +action. Obviously, things get more complex than this, and it often depends, but when you’re starting out you should plan things with this equation in mind.
Where would you rank the other "clutter" cards (like Cultist)? I'm guessing right below the cursors? Then there are also the discarders (Militia, Ghost Ship, Rabble). I'd put those below the clutters, I think.
In the same interview, olneyce said that Saboteur is one of his top-5 most hated cards. I'm guessing that's because it's one of the "cards that warp the game and overwhelm other strategic decisions". I've found it to be really powerful, and hard to play against without getting one yourself. One game I played I was making horrible decisions and getting brutally beaten. My opponent had already gotten 3 Provinces, and I didn't have any. I bought a Saboteur, and got lucky by King's Courting it a few times, reaping havoc on his deck, while also trashing his Provinces. That became my sole strategy, and once I had him crippled, I was able to buy some Victories and end the game. Seemed way too powerful that time, for sure.
Also to follow-up about the "bad trashing"... if oneyce was talking about using a trasher in a bad way, why is that still better than +action? I'd think that a +action that lets you use more of your other actions would be better than buying a trasher but not really using it?
