Just a quick question, what are some of the rarest cards in terms of pulling odds out of a pack that has been in the hobby? Was it the Gold Stars? And just for fun, in the future I think it’ll be exciting to have 1 card out of a set that’s super rare, maybe rarer in terms of Rainbow Rare pulls nowadays - think of a Willy Wonka Golden Ticket rarity pull 
What’s that like a million chocolate bar to one golden ticket?
I read this and left E4…
30 minutes later I still had little Charlie and his “I’ve got a golden ticket” singing in my head so I had to come back.
I never kept up with pull rates myself until XY when I started opening packs in mass. I tell you what, the Gold Ultra Necrozma was hard. It is not the same rarity as the other secret rares. I opened 1500+ packs and my wife managed to pull 1 in the last 5 packs we had. Surely it is not that hard to pull, but it would take a lot of elite trainers to know for sure.
Is it generally assumed or has it been verified that pull rates in sets that aren’t available in booster box form are the same as sets that are?
I can tell you that for Generations, Shining Legends, and Dragon Majesty they are not. Most of the time, pull rates are different. I cannot say off the top of my head they are all different, but usually pack composition is different as well.
I reckon no damage Ninetales would be up there. Also, pulling any no rarity holo comes to mind given the scarcity of sealed product.
