Yeah, I'm up to date with all of the current mechanics, besides the top decking one for the Slyvian archetype. It's hard to recall when I quit, but I think it time during/shortly after the wind up format (as in, during wind up OTK and after Wind Up Hand Loop. It was when the set that had Noble Knight Medraut dropped, and I was kinda frustrated at the amount of hype a terrible deck I wanted to play had, and was (and still is) over costed to high hell.
Buuuut that's besides the point. I'll look more into this and decide if I wanna pass or not.
