As for the rest, we're looking at the natural design trend we've been seeing ever since Dark ConfidantDark Confidant: Creatures are easily removable, so it's easy to put powerful card advantage mechanics on them for cheaper than you'd see them otherwise
This mechanical niche has heretofore been a bit of a hidden gem, especially the idea of building around it but that seems to be changing now, and quickly
As the final mythic rare in the modal DFC cycle, Agadeems Awakening takes the flexibility of these cards even further
$200 List The $200 list adds some powerful planeswalkers such as Tezzeret the Seeker and Ugin, the Spirit Dragon which benefit greatly from proliferate
