Pokemon mobile ripoff 'Master of Monsters' airing ads on YouTube

This is so outside the realm of usual rip-off. Not only are the people behind Master of Monsters ripping off just about everything Pokemon, now we see that even their advertisements rip off other Nintendo IP! Master of Monsters has been running pre-roll ads on YouTube, and I just don't see how they've gotten away with it for so long. It's a complete rip-off of Pokemon, yet ads are approved and no one has tried to stop them! Thanks to Chesumori for the heads up.
