Is MD Teeg really needed after the banning of MT? As a one-off he seems too random, and if you get survival online you could search him or start chaining VVs, which I feel is better in almost all situations.
I can say, as a NO player facing Teeg, that MD Teeg is retarded. He's nice at shutting down EE and some other strategies that often are boarded in or used against creaturebased decks.
