Which limited pack ?

Hey guys,
I’m a bit confused about which pack to choose… I got delugazar from anniversary pack… now I have 100 gems.
Should I roll them on Halloween pack or anniversary pack ? Pengunator or the sleep/poison legendaries ?

I think depends on what kind of team you’re trying to form. I was trying for a poison team so I waited to Halloween and I’m very pleased!

Well you might aswell do at least 1 pack on the Halloween seeing as your guaranteed a legend. Up to you what you do with the remaining 50
