I expect a wide variety of Curve Sentinel decks there, some basic builds, others with Total Anarchy, Micro-Sentinels, etc.
Fantastic Fun decks may be well represented as well. As well as just about any type of deck that has Doom in it. Doom has become quite the popular control figure hasn't he?
That and EMS as well, Teen Titans, B&B, TNB...
I expect a wide variety basically, lol.
