The Centurions are excellent cards. I received a free deck from the competition, so I had the privilege of breaking them in and trying them out before everyone else.
The quality is excellent, and the stock and finish are perfect. Unlike the 1st ed. Guardians, these do not clump at all. The handling feels extremely similar to the Guardians.
Compared to Wynns, I would go with Centurions. They are much cheaper, and are well rounded in both flourishing and magic.
