It was announced that Mister Donut in Japan will collaborate with Pocket Monsters in celebration to celebrate the 50th anniversary of Mister Donut. The Lucky and Good Luck! Scratch Card Campaign (ラッキーといいことあるぞ！スクラッチカードキャンペーン)" will be held for a limited time starting from Friday, December 4th, 2020.

For every 1,000 yen (tax included) spent on the campaign, customers will receive a Lucky Scratch Card, and if they win, they will receive one of four original Pokémon clear files. In addition, for the first time ever, Mister Donut will be distributing a special Lucky that can be used in Pokémon Sword or Shield for Nintendo Switch. Regardless of whether it's a win or miss, all Lucky Scratch Cards can be entered in-game with the serial code written on them to receive a Lucky.
