I'm sure 75% of the community here already knows better but for those who don't know... the first rule of DotP12 (and Magic in general) is to keep it at sixty cards! Literally, 1/3 of the players I get matched against play with too many cards. Unlock a new card? Go back and take a card out. Magic is a game of strategy and luck. What better way to strategize with the cards you want and improve your luck by playing with just the minimum cards available. The top players in this game (and in real life) use sixty cards. Can't tell you how many times I've beaten someone who has asked me for help where the first thing I've told them was ... cut their deck to sixty cards. No more no less.
