So how many featured game modes are there in rotating queue?

These were the ones I counted:

Urf One for all One for all mirror (Howling abyss) Hexakill Hexakill tree line Doom bots Acension Black market brawlers (The one with upgradable minions) Nemesis Blige water ARAM? Poro King

Potentially 11 game modes. So roughly 3 months for a full rotation, assuming they're not random.

Did I miss any?
