Understanding the Unfinity set
How to know if a Unfinity card is legal?
The Unfinity set will be released in October, being a set focused on casual games and pure fun with your friends. However, this unset, unlike previous ones, will not come with a silver border, and some cards will be legal in eternal formats.
As there is no longer the silver border, what will define if a card is legal or not in the formats will be the absence of a nut as the set symbol.
If there is a nut in the set symbol, the card is illegal in formats. If it doesn't exist, then the card is legal.
Currently, Unfinity set has 373 cards if we disregard tokens and different card versions/promo. Among them, 140 of them are legal in Commander, Legacy and Vintage, and only 65 are legal in Pauper (only the common ones among the 140).
