SOB Clans will always be popular.
They level the playing field by taking away the advantages of clans like Rescue , Huaracan , Roots and other clans with nasty bonuses.
Also Oshitsune isn't banned as opposed to lot of other stable 4* cards.
True about Oshitsune , but Nightmare as opposed to Piranha is also that Piranha are not as easy to Half Deck.
Nightmare on the other hand are pretty easy to half deck with.
Hmm, I thought it was some kind of counter-meta to the new bonuses of Huracan and Riots, but I guess it's kinda normal then
Nooooo, Riots aren't anywhere near threat level.
They've got a Solid 3 Star in the form of Weasel face and they have a good 5* but they're about average.
Huracan is not as strong as they used to be.
Nightmare / SOB make it easier to deal with lots of clan Bonus'es and such. Also easy to half deck with unlike the mainly mono Piranas
