Truth be told, I have a weak spot for Secret Mage. Nailing a Counterspell on a big ol’ Mass Hysteria feels satisfying, as does Potion of Polymorphing some big hulking Deathrattle-Taunt.
But yeah, make no mistake, it’s a strong deck. You were facing the low ranks, so of course you won, but it’s entirely possible to keep a huge streak up until you start facing certain Reno and/or Warlock decks.
Great matchup against DH’s though - Flakmages are nuts.
