During Round 7 of Pro Tour Khans of Tarkir, competitor Lee Joong-Won was disqualified from the tournament.
Below is a statement from head judge Toby Elliott regarding the disqualification:
"During Round 7, Lee Joong-Won used a Wooded Foothills. In response, his opponent cast Jeskai Charm to put Lee's only creature on top of his library, at which point Lee tried to skip the resolution of the Wooded Foothills ability. After interviewing him, we determined that the error had been intentional so as to redraw the creature, and disqualified him from the tournament."
