Female would be perfect! I'm currently making a 5th gen team with Chandelure, Milotic (Shiny), Jellicent (Shiny), Roserade (Shiny), Nattorei, and Hydreigon (Shiny)... Jellicent with Water Absorb would be SO perfect! Then I'd just need Naive Hydreigon and shiny flawless bold Milotic in a dive ball (for Dragon Tail it needs a 31 attack iv, and I think the only easy way for one of those is 5th Gen abuse on Route 1). I really love the idea of using Female Jellicent and Milotic together--they're like the bulky water Queens!
