Unfinity is the 5th set in the joke themed "Un" sets that Wizards of the Coast has produced.

Set in space, the set revolves around "Myra the Magnificent's Intergalactic Astrotorium of fun". Many of the cards will have a space themed look to them.
 

Unlike previous "Un" sets, Unfinity will be completely black bordered. Also, some cards in Unfinity will be legal to play in eternal formats like Commander, Legacy and Vintage! Any cards with the trademark oval planeswalker stamp on the bottom can be used in those formats!

 

Just like Unglued, Unhinged and Unstable, Unfinity will be bringing back the highly sought after alternate art basic lands with a new space themed look! New to Unfinity will also be alternate art space themed "Shock Lands"
