Three massive factors are driving these values into the stratosphere
There aren't many truly valuable cards from seven different sets so far (not double-counting for base and foil releases), but there are some standouts if you were lucky enough to get in on the Ghost of Tsushima drops
I have been extremely vocal about Phyrexian Altar being my favorite card since I was a kid
Hades - Lord of the Underworld has proven to be a popular card due to his recursion ability
By being Jeskai, which is mainly Blue-White with a red splash, you also have a cleaner manabase and your three drops, like Narset, Parter of Veils and Teferi, Time Raveler, are better suited against combo decks and control mirrors
This week Im sharing my deck built around Minsc & Boo, Timeless Heroes
