Since "Kamen Rider Zi-O" (The new Kamen Rider for 2019) was leaked and after seeing this ( https://www.youtube.com/watch?v=Sa5oD6hKdvo ), I think the new Sentai for 2019 should be "Oritsu Sentai Knightranger", the first ever medieval-themed Sentai!
Just an FYI, when you replaced your images with my cropped out versions of Revolver Tenrai Senpuujin and Revolver Gourai Senpuujin on your sandbox, you accidently placed them over Tenkuu Gouraijin and Tenkuu Senpuujin instead of their respectful predecessor images. Just thought I'd tell you that.
P.S.: There is a cropped out version of GoZyu Gokai-Oh (my work) and Killer-Oh (courtesy of PowerSubZero).
