During the Revenge mode where you have a team of two planeswalkers in addition to yourself, Garruk killed off my teammates. I was about to call it quits since I did not have the cards to beat him. However, he drew a scheme card and the game ended with me as the winner; felt very random.
The game didn't let me see what the scheme card was. Is there a scheme card that the enemy would draw that would allow for an "instant win"?
