As for the decklist itself, let's take a look and see just what kind of shenanigans we can get into
The deck loses a lot of steam when Galadriel gets shut down, but as long as we can ramp out two lands with her before she goes it's easy enough to recast her and keep going
Cards like Bonecrusher Giant and Murderous Rider performed well, but I always expected them to, and their power levels are kind of in your face, so Im not going to mention them here
Before this change, Wizard Mentor was a first pick card which could save your creatures from creature kill spells, allow you to reuse the bevy of 187 creatures in the format (Ghitu Slinger, anyone?), and at worst case scenario allow you to play emergency defense
(Equipment, Auras you control, and counters are modifications.) The +1/+1 counters on Costume Closet won't affect it unless it somehow becomes a creature
When playing in paper, manifesting a DFC would normally leave the reverse side of the card exposed, but checklist cards and sleeves exist to solve this problem
