First off, that's offensive. Please watch what you post.
Second, he's nothing like Shulk in anything besides appearance. If anything he's closer to Roy or Corrin, but even then he's unique, using a different fighting style and being able to turn into a full dragon compared to Corrin's semi-transformations.
He's also a great way to promote Nintendo's partnership with Cygames and Nintendo Mobile, which only continues to grow larger as Nintendo releases more mobile games and they become more popular. Dragalia Lost is Nintendo's first original IP on mobile, and adding the main character of that game into Smash would be an amazing way to promote not just the game itself, but Nintendo's entire mobile lineup.
Not like you care given the dismissive tone in your post, but I'd say he's one of the top contenders for this DLC cycle.
