Alright, just some heads up on my XD run so far:
-My first reset (done months ago) was Poochyena - Calm - 20-29/10-19/0-9/20-29/30-31/30-31. I will keep a copy UT and evolve the other on Emerald (to ensure it keeps Intimidate), then Tutor it.
-Today I reseted for Duskull and got a somewhat decent one. It has a +SDef nature for sure (it lowers either Atk, Speed or SAtk, none of which really matter for a Helping Hand Duskull), and all in all decent IVs. I'll update when I have narrowed them down.
-Saved just before the battle with Mawile. Going for it next (will auto reset if it doesn't have Intimidate).
