Please remove or ban thunderbond vanguard. It’s absolutely busted and makes the game completely unfair. Every game vs white is dumb because they’re going to play this three mana, oh look I went from nothing to swinging for over 100 damage, win the game out of nowhere card.

Another suggestion, is enable users to ban one or two cards in the format. So essentially users pick a card and the matchmaker will not matchmake you against decks with the chosen card. Then MTG arena admins can look at the statistics of what cards the majority of players hate as a form of crowd sourcing problems with balance or un-fun cards.

You guys kinda already are trying to find out if users are having a good time or not, but the happy smile vs sad face system kinda will give skewed results because players will likely just put a sad face every time they lose. Their bad experience could be a problem with the shuffler, an unfair card, or something the other player was doing like playing too slowly.
