- Slightly improved DestroyAi for Strip Mine and Wasteland (AI should not sac-destroy a land unless it has a mana-producing land to replace it with, as well as at least a couple lands in the hand and on the battlefield combined, or enough mana-producing lands on the battlefield in general, otherwise it's too risky to mana-lock yourself early in the game). Further improvements are welcome.
