Memory Crunch!
The default hand size as the game begins is four cards. You
can increase your own limit before play begins by spending 4 life per card,
or decrease your limit still further and gain 7 life per card reduced.
Thus, if you want to start with a standar seven-card hand, you would spend
12 of your 20 life and start play with 8 life. If you play with a three-card
hand size, you begin with 27 life; at two cards, you begin with 34 life.
During the turn you can increase your maximum hand size at a price of 6
life per card, or reduce your maximum and gain 5 life per card.
