The True Rarest: The modern answer is a one-of-one serialized card

Chilling Reign is the sixth expansion of the Sword and Shield series and will hold 198 cards excluding the Secret Rares, featuring Pokemon from the Sword and Shield Expansion Passes: The Isle of Armor and The Crown Tundra

It is a singleton format, meaning you can only play one copy of a card in your 99-card deck (excluding basic lands) and your commander that is outside the main deck

Butterfree also has a Retreat Cost of one, meaning that it can get out of harms way fairly easily after it is done, providing care for your Pokemon and landing a few hits along the way
