Wildfest was a Hearthstone event that served as a celebration of the Wild format. It lasted from February 19th to March 11th 2018. Its main feature was the Wild Arena, which allowed cards from any set to be drafted in an arena deck. It also had themed Tavern Brawls.
Features[]
During the event, the Tavern Brawl and Arena screens were decorated with the same vine overgrowth Wild menus are, although they lacked the darker color scheme.
Wild Arena[]

During Wildfest, cards from all sets could be drafted in Arena decks. This highly increased card pool made for a chaotic meta.
While any set was open to draft, all normal card exclusion rules still applied. For example, you couldn't draft 
C'Thun, Vicious Fledgling, or Hero cards.
