I've been playing for a while now, and it's really a great game. However, I'd love to try out some card combos/ heroes that I don't have. So does anybody know about a way to get a sandbox mode of sorts, so I can try out all the cards and all the heroes against bots? This would be super helpful to get to know what kind of stuff I should be saving up and getting. Thanks for the help👌🏻
(On iOS by the way)

Best thing I can recommend is to play the daily challenges; they often include cards I've never had the opportunity to use before. I just wish they were repeatable (even if no further rewards).
