Jcm your asking us about Nu? Wow and though there is 3 very sexy looking answers in my very short experience of Nu I found a Pokemon I would originally never use.
Ok I can't remember the exact set maybe this is it but I'm on holiday so I don't care smog pb will be similar.
What's great about this Pokemon it looks so stupid but can be a real pain in the bum.
Ability: which ever it has -__- I may have to get back to you on that one.
252hp 252def 4spdef
-Hidden power- which ever supports your team how bug is usefull in Nu though
Ruencluss of Nu just bulkier.
This guy is great and all round bulk is great plus fills up your psychic spot on the team for the infamous fight,psychic,dark core.
She meets all your requirements and is fun to use congrats on 2nd place btw Jcm
