Help breeding a good death pet

I'm a level 39 death school and I have a lovely leopard right now with balance and life resist and I thought it was pretty good but my friend told me that double universal resist and adding attack or something like that was better I also am hoping it can have a star jewel socket because I have a deer knight jewel for ultra pets and I was wondering if anyone could help I don't really have anything to give except for some treasure cards.
