Opened up over 700 packs myself got every card. The no duplicates helped a lot Best i got was 1 reg epic 1 rare 1 golden epic 1 golden legendary. Didn't open any packs with 2 legendaries.
Best pack i got was Golden Uther(Legend), Golden Obsidian Statue(Epic), Snowfury Giant(Epic), the Dreadlord that does aoe each turn(rare), and Righteous Protector(common)
The cards alone are good ones aside from the snowfury which i won't use anytime soon. Nice that it's an 11 drop for evolve/devolve now in game but meh. Opened up too many packs didn't screenshot because i wasn't going to screenshot every legend i got in 700+ packs lol.
