Leaf Cup

The Leaf Cup is a cup in the Mario Kart series, introduced in Mario Kart DS. It exclusively features classic courses. The Leaf Cup usually contains courses from the Flower Cup and Star Cup of previous games, with some occasional Special Cup courses, though it features a sole course from Mario Kart: Super Circuit's Lightning Cup in Mario Kart DS, and a sole Mushroom Cup course in Mario Kart 7. The Leaf Cup is slightly more difficult when compared to the Banana Cup, akin to the Star Cup. The cup's emblem is a Super Leaf, though its design was changed starting with Mario Kart 7 to match its redesign from Super Mario 3D Land.

Trading Card info
"The Leaf Cup takes us back to some tracks that are definitely fan favorites. Go retro while you find shortcuts at DS Desert Hills, avoid the giant Thwomps at GBA Bowser Castle 3, blast over the river at N64 DK's Jungle Parkway, and fake out the Chain Chomp at GCN Mario Circuit."
