At Day 1 of the Magic: The Gathering Mythic Championship VI, Magic Pro League member and Mythic Championship I winner Autumn Burchett was asked to remove a couple of cards from their deck.
Over on Twitter, Burchett shared a photo of a Therese Nielsen Forest and Island with the written messages "No terft on Gruul Turf" and "Trans rights are human rights.", and said that the tournament officials instructed them to remove the defaced Therese Nielsen lands from their deck.

Burchett went on to say that the decision was Wizards of the Coast's, and has nothing to do with the judges, but no explanation was provided to why they asked them to remove those cards.
Someone on social media pointed out this ruling:
Artistic modifications are acceptable in sanctioned tournaments, provided that the modifications do not make the card art unrecognizable, contain substantial strategic advice, or contain offensive images. Artistic modifications also may not obstruct or change the mana cost or name of the card.
These cards don't constitute strategic advice for Magic, and they don't contain any offensive images, so it's still unclear why the tournament officials asked her to remove them. "Gruul Turf" is an actual card, so that could be part of the reason, but I can't think of any backstory that would make removing that Island justifiable.
The Mythic Championship VI takes place at November 8 to 10, and the formats are Throne of Eldraine booster draft and Standard.
