I can tell that you played Magic just from the half cards following their card text to the letter, meaning that if you lock them in place, they stop being awesome and resetting to 0 and start growing instead, giving you really wonky numbers.
I had fun playing this, but on the second play through without hearts I realized that it probably is a bit too random for me - there's so few hand cards or cards in general where you can make an informed decision, and it is next to impossible it seems to really sculpt a deck like you want it because you'd have to get rid of so many starter cards. Why not go all the way and have me pick a number I want to stand at like the AI has and resolve game play semi automatically?
