In case you aren't up to date with such things or just forgot, today starts the first YCS after the rule change in the game. It promises to be an important landmark for the metagame because of that (although gaov will bring a couple of things to the table after that, but not that much), so if you are interested in it remember to catch up the coverage and feature matches as they come up (not up yet at the time I post this but in a couple of hours until late at night for europe they should keep coming up).
