It's pretty much just decide what element you want to use for him, plus a weakness (reflect is usually the same as the element, then there's resist which is a compatible element).
Personally, I'd suggest Garu (wind) because it's the closest to earth that the game has, though Zio (electricity) could work too.
It's up to you though.
