Commander Legends, the first-ever Magic: The Gathering Commander set designed to be drafted, is set to release next month, and official previews are expected to be out this week. Today, several new cards from the set have been leaked, and they include two Planeswalker Commanders that both have the Partner ability: Tvesh Szat and Jeska.

Redditor Jamesboyadvance said that he was looking at Commander Legends sealed product on eBay, and stumbled on a listing, and saw images of the new Commander Legends cards. Check them out:
Here are the translations of the text of the two Planeswalker cards leaked:
Tvesh Szat 4 Loyalty
Jeska 2R 0 loyalty:
Szat's ultimate looks powerful but overall this card is well-balanced. This Planeswalker will most likely be used in sacrifice strategies. Jeska seems to rely heavily on casting another Commander before she can get loyalty.
It looks like the set will feature a good amount of legends that have the Partner mechanic. Wizards of the Coast will most likely reveal more cards from Commander Legends soon, so expect more spoilers this week.
Commander Legends product and events will be available on Magic Online on Thursday, November 19, 2020.
