Analyzing the Recent Success of Anti-Meta

Whether you are using Tech Genus, Malefic Beats, or even Anti Monster Beasts, you are using an anti-meta deck.  The obvious definition for anti-meta is any deck that seeks to counter the current meta.  Not too long ago, Gravekeeper's did that job very well.  Now they seem to be eclipsed by more battle oriented decks.  Where GK's depended on Necrovalley to shut down graveyards and gain atk/def stats, this new breed of decks use specialized monsters with advantage generating effects on their own without much reliance on other cards.
