Hi! I've been seeing other people mentioning it too, so I'm making this suggestion here.
We need a game mode where we can play just for fun (with humans, not Sparky bot) in fair matches. Ranked is for competition, so we have all the meta decks there: the goal is to win. Play could be just for playing, but since it has the daily achievements and wins, we see meta decks there too and we often get matched in unfair matches. So if we get creative, and brew new decks, and we want to give them a try, we're matched against meta decks anyway, even in Play mode. So there's no game mode to play just for fun. In that way, there's no place for creativity. Even if we create new decks, we can't try them in a fair match, with other junk decks.
Since Play is usually a place to earn the daily achievements and wins, we find there meta competitive decks that only play to win, regardless of how repetitive and boring that match could be (Ranked is the place for that). Or players that only want to cast / destroy / attack and very likely to concede after a few casts (equally boring and time waster). Neither of those cases are fun. So my request is a game mode like Play, but without achievements, daily wins or any goal earned. A game mode that doesn't change anything on the player's stats. Just for fun.
Thanks!
