In a Modern PTQ you are head judging, your Deck Checks Team Lead brings you a decklist. At the bottom of the lands there is an entry of “4 Darkslick”. You confirm that there are only two cards legal in Modern with Darkslick in the name: Darkslick Shores and Darkslick Drake. She believes that the player intended Darkslick Shores because it is with the lands and not likely to be Darkslick Drake. The decklist is otherwise legal.
What do you do? What infraction, penalty, and fix does this situation require, if any?
Judges, feel free to discuss this scenario on Judge Apps!Answer
This downgrade has been available to head judges in the past, but the recent small change to D/DLP has made it more clear for head judges that it is acceptable, and in fact encouraged, to downgrade in this kind of situation. It was a simple mistake and was not intentional by the player with the aim of gaining an advantage.
