goal of this solitaire variant is to empty your hand and have no cards
left in play. If you run out of cards, or take twenty damage, you lose.
You may not use any discard spells or abilities. Your creatures may
attack each other. Lands and other permanent cards can be destroyed
using the appropriate spells. You may also destroy any card in play by
paying its casting cost in life. Lands may be discarded from play at a
rate of one per turn, at the cost of one life; additional lands may be
removed at a cost of eight life points each.
