About half way through, and still time to join for some games! We have had a good amount of people on the past few days especially, so it's been very fun.
For a long time Shekky Ducky was in first, having a lot of success with his Desolation Row straight flush clubs deck, and just recently was surpassed by Khudzlin with his infamous, often-seemingly-unbeatable 108 WD Rabbit Fu deck.
I've played both against and with quite the variety of decks so far, and hoping I will find some more matches with some of the folks overseas the next couple weekends.
As a personal side note I am having a lot of luck with a law dogs blessed deck (even though I've only played it a couple of times in the league so far), that is a ton of fun and seems very solid. I had been playing one with Putting The Pieces Together (both a heart-flush version and a 3-value version), but got rid of that card entirely and it's been doing much better since. I think blessed have potential to be competitive, 'top tier' with the right setup.
