It was then that Time Walk transitioned into my new favorite card, and at $85 a pop, it wasnt going to be easy to acquire and so I embarked on a journey of finding Magic tournaments to compete in, win a few dual lands here, a Mana Drain there, and next thing you know, Im competing in big tournaments to win Power.
