The first MTG cards from Mystery Booster: Commander Edition have been revealed by fans who got to play with them at MagicCon Amsterdam, and there's some truly wild stuff in here. Whereas typically, a commander deck is built around a commander, often seeking to keep it safe on the board while it provides value for your other cards, a sorcery is always going to be one-and-done. And with Ashaya's Enduring Bond, you need to think carefully about how many low-CMC cards you include. The last thing to consider is that a legendary sorcery can only be cast if you have a legendary creature or planeswalker already on the field. I'm not altogether sure that Ashaya's Enduring Bond isn't just a terrible card, but it's definitely pushing the boat out in terms of what can be done in the format.
