Hi, I've been trying to get Infiltrator on a Zubat, and I thought of breeding a female Crobat with a male Noivern with Infiltrator. Will this work, or do I have to do something else? Thanks!
No it wont
The only way you can breed a zubat with infiltrator is if you already have someone from his evolution line with infiltrator.
Zubats with Infiltrator have a small chance of appearing in hordes or by dexnav chaining.
