I pulled 8 legendaries out of 44 packs (24 core 20 expansion), coming out at around 1 out of 5.5 packs which isn't bad. Unfortunately they're 1-ofs and not all of them are 'power' legendaries (Soul Stealer for one feels more like a Gold card).
Bloodcraft:
1x Soul Stealer
1x Bloody Mary
Forestcraft:
1x Rose Queen
1x Crystalia Tia
Dragoncraft:
1x Fafnir
1x Zirnitra
1x Dark Dragoon Forte
Swordcraft:
1x Alexander
I've also gotten 16 Gold cards, but again, most as 1-ofs. The only 2-of is a Timeworn Mage Levi.
Should I reroll? Seems like I pulled a decent amount of stuff, but rather spread out.
Do you know what deck you want to go for?
Forest and sword use a lot of legendaries. Face dragon just needs the three forte I think? Some aggro blood use Bloody Mary but it's optional based on the type.
