I really like playing the mid-week magic events, and signed up and started this weeks Jump In on the start day yesterday. I picked Roku and Powerful like you normally would. Then, upon playing and drawing too many lands, I checked the decklist and 29 on the 40 cards in my deck are lands. This makes the deck unbearably unplayable, and I’m confident the powerful half of the deck is what bugged bugged as I have no green cards other than lands. I play primarily on my iPhone and signed up for this event before whatever update you pushed on Tuesday.
