Technogeek5000 asks this relevant question:

"Several months ago Cephalid breakfast was a tier one deck... it had multiple top 8's at nearly every tournament. Belcher preceeded Breakfast and had a large number of top 8's... and before Belcher, TES was putting up impressive results.

"Occasionally you will see a combo deck in the top 8 of a tournament, but there are no combo decks currently in the format that are higher than tier 1.5. Solidarity fell off the radar and Aluren will occasionally place. Control decks and aggro decks dominate top 8's, but it seems that combo will only put one (1) player into the top 8 of a medium/large-sized tournament or sometimes none at all. Why is this?"
