No, I haven't been in Utrecht in a while. My financial situation wont let me. I don't think we've met yet.
Personally I'm not set on Fireblast. I don't like risking drawing them in early game or having them in my opening hand. I have enough confidence in Zoo's capabilities to survive the midgame that I don't think Fireblast is really need as a finisher either.
On Gaddock Teeg. I dont know how good ANT is atm. I think I would put them in the sideboard unless ANT and other combo are still unbeatable without hate game 1.
