You get Wildcards by opening boosters, competing in events, and winning games to beat your daily and weekly challenges - so if you're short on Wildcards for the shiny new Arena deck you want to build, the best thing to do is get playing with the decks you already have

Violet era with the release of Collect 151 Slim Booster Box
This card is the biggest reason why I dont have cards like Azor, the Lawbringer or Etali, Primal Storm higher on the list, as playing expensive creatures without an immediate impact will be tough when your opponent can gain such a tempo and mana advantage with Ravenous Chupacabra
It wont always be free to invest the mana into your Treasure Map in the early game, and the card can be a poor draw in the late game like any mana rock, but the ceiling is plenty high
