I am genuinely interested by what words carry and in your case the kind of people they are going to attract. I actually write a bit on that. If you emphasize a lot on ninja/ elite etc... I would guess you will attract a lot of immature people who have ego probably bigger than their talent.
If you look at the phrasing of Y Combinator or even Facebook ads for developers you can see that even if they add some words to be fun they are careful about their use not to send the wrong signals.

Anyhow I wish you the best for your initiative!
