I'm wondering if I can do waterfiends efficiently. I have 80 attack and strength, and 89 defense. I just remember that not being adequate last time I played, I always got destroyed when I went. However, if this isn't the best way to get crims without going broke, I'd like to know. I doubt it's changed, but you never know I guess. Also, if I do go to waterfiends, how stable would a z spear be? I'm short of cash (always), and I don't want to lose a bunch on it once I'm done.
