Cool article and fun interview! I need to broaden my horizons a bit, maybe proxy up that Tezzeret list. Looks fun.
I have a love/hate relationship with that deck. I love chaining Thirst for Knowledges into Thoughtcasts and going nuts with broken spells. But I HATE some of the hands that deck gets. One artifact and two Thoughtcast, or worse yet zero card draw and all non-basic lands, die to a Wasteland.
The list is extremely powerful at times, but in my opinion it is highly vulnerable when compared to Grixis Thieves or many other similar decks. Seat of the Synod makes Null Rod, Stoney Silence, Wasteland, Energy Flux, and even Kataki, War's Wage such a humongous liability, it's downright terrifying to face.
One of my absolute favorite things about this list is the Trinisphere in the sideboard. Beyond putting the screws to Storm decks, that card actually has many applications. I've brought it in against Delver, BUG Fish, and several other decks centered on or filled with cheap spells that are highly disruptive to the Tezzcast strategy. The deck plays such a large amount of mana that much of the time the deck can just ignore Trinisphere. All the while Trinisphere is playing double-duty and acting like a Defense Grid during your own turn.
I'm sure that I'll catch some flak for this, and that's fine, but I really wonder if it's possible to make Trinisphere a more important part of the deck's strategy. Being that it's restricted makes it difficult, and there are some inherent drawbacks, but I was amazed at how often I was bringing the Trinisphere in and how often it made me win the game.
Thanks again for reading. I just finished my first article for MTTGoldfish.com and I'm super excited about it. MTGGoldfish has been growing steadily and gets a much larger amount of page views than I'm used to. Hopefully I'll be able to inspire some players to give Vintage a go and we'll get more tournaments to fire.
