Rule 107.10
Official source text from the 24 January 2020 Rules release
A type icon appears in the upper left corner of each card from the Future Sight® set printed with an alternate “timeshifted” frame. If the card has a single card type, this icon indicates what it is: claw marks for creature, a flame for sorcery, a lightning bolt for instant, a sunrise for enchantment, a chalice for artifact, and a pair of mountain peaks for land. If the card has multiple card types, that’s indicated by a black and white cross. This icon has no effect on game play.
