There are some extra rare variants that can show up exclusively in the token shop. They're pretty rare though, even series 5 cards are more likely to appear there. Confusingly they are called "Ultimate Variants" even though there are cards with regular variants depicting the version of the character from the Ultimate Universe that are also called "Ultimate Variant"

Aww, didn't realize the new location says "cards that cost 6" rather than "6-cost cards" so my She Hulk Infinaut plan won't work quite as well as I wanted. Probably still pretty solid though.
