As a couple have stated. Matchups seem lopsided, so it feels like you need to high roll when you cue up for a match. That and many matchups seem to be determined by draw order and scoring the best starting hand. Just think how much a matchup swings when geist is drawn on curve. Or when a druid gets wild growth into nourish. Don't forget the ever popular prince keleseth on curve. Many matchups feel similar to the freeze mage vs control warrior match up. Deck variety is great but knowing you are going to lose no matter what you do after turn 3 or 4, kinda sucks.
