Yeah, this was my impression as well. Hardly anyone ran black and white was tricky due to the expensive flyers. I don't think I ever lost a match to white. I pulled two favorable winds, but I still didn't play white because the cheapest white flyer I had was 5cc, and I only pulled a grand total of 10-11 white cards. Green seemed to do really, really well though, especially when paired with red. G/R and G/B are going to be pretty popular in standard and limited. The guy who placed first had G/R, and my friend who placed second ran G/B. I really wanted to run green to negate enemy flyers, but the cards just weren't there. I probably still should have splashed it, but I was pretty nervous due to it being my first time. Next time I'll be better prepared, for sure.
Also, favorable winds is utterly ridiculous in limited, especially with those ravens. I had three of 'em, if I drew at least two and one FW the game was basically over.
