Thia video is great but it's like it was made before dr season 1

The main characters are the ninja which is okay but like there is aspheera and pythor which is cool but no Overlord or Samukay,Skales,Morro,Chen and I get that they are defeated but this implies that this whole video happened irl in ninjago.The new ninja are also absent for most of the video I get that this is for the 15th year thing but aspheera and nelson more in this then the litteral new main characters.This feels like it's a promotion for crystalized or was made for dr season 1 part 1. ...
