The release has happened. Battle for Zendikar is legal in Standard. We’ll be seeing the earliest results for the new format this weekend, which will increase the prices on a few cards. Then the Pro Tour will cause some major swings, and Khans of Tarkir will be at its highest price index since its release—the perfect time to sell.
It’s not too late to pick up cards from Khans block if you haven’t fully stocked your speculation coffers yet. The last several months here at MTGPrice, however, have seen a plethora of articles dedicated to Khans of Tarkir block. Check out the blog archives for a ton of opinions and thousands of words.
I want to look even further back today. Nobody cares at all about Theros block right now, or M15 for that matter, and that’s exactly why those sets are perfect places to look for cards to scoop.
