It's nothing too complicated, but only available in gen 3, which not a lot of people know RNG on.
Anyway, with the new Mega Kangaskhan, there's the awesome usage of Seismic Toss with it's ability, Parental Bond. If you are up to it, I'd really like a 31/31/31/X/31/31 Kangaskhan with Seismic Toss. If you're up to doing more than one, Adamant and Jolly. Otherwise just Jolly is fine.
