Have you been following the Hero's Path?
If you don't know what it is, it's a cool little "campaign" released by Wizards of the Coast along with Theros block. At Game Day for each of the sets you take a different challenge, whether it's fighting the Hydra or something else. It's pretty fun and different, allowing you to take a team approach similar to Archenemy.
Of course, this is something that was mostly for casual players, and that's okay. Most of the tournament grinders I know weren't super excited about it, but they're not the intended audience anyway. In fact, one of the great things about Wizards is how they can appeal to so many different segments of the playing population.
Anyway, I know one group that did enjoy the experience, and that's the awesome folks over at Loading, Ready, Run. A video of the group walking the path of the hero was posted to the Mothership on Wednesday, and it's well worth a watch as always. You can find it here.
