Cabal Therapy, Game 1, Turn 1, naming a card blindly

Does anyone else do this? And what do you usually name if you have no clue what deck archetype your opponent has? I've been naming Swords to Plowshares and it seems I get a hit about 1/5 times. Turn 2 I sac a Wall of Blossoms and if they have 2x of a card in hand at this point, it's usually pretty devastating.
