Oracle hasn't been gone that long that the 2 more HP is anything different.
Huracan have become increasingly popular in ELO after their last couple releases. They still lack an SOA or SOB, but quite frankly they don't need one. This is largely because their 2* are very competent, and they've got fine choices at the other star counts to fill spaces according to your other half. Kinichaw has an obvious weakness, but she is still incredibly threatening.
Zhu Tang is only player banned this week because of FPC actually being popular last week. Same reason that Kerozinn Cr is high in the format election this week. 5/3/3/2 splits were their most popular choice (most having Kero, some also with Marly).
Jungo certainly haven't gone anywhere. They were incredibly popular early in the week, and despite dropping slightly as the week went on they have still been around enough to be noticed.
This may not be totally accurate, but the most common clans I've seen in the last day or two have been Huracan, Sakrohm, GHEIST and Rescue. This is just based on what springs to mind, and isn't necessarily 100% true (nor the same for everyone).
The Huracan bonus favors aggressive play (on both sides), which I think is a good thing. Kinichaw is indeed threatening but I actually prefer the stability of Lumber Jack. (Is that like preferring Ongh to Troompah?) I agree with Joe-- Huracan are already quite strong without SOA or SOB because of their low-star cards and their bonus.
GHEIST has become stronger as more people have acquired Mechakolos, who is the top votegetter in his first week on the ballot.
Zhu Tang being banned seems like a fluke, but Kerozinn Cr is also getting a lot of votes this week. I guess the Kerzoinn/Zhu Tang/Shifou/Kusuri half has gotten some serious attention.
