Welcome to New Phyrexia! I love this set so much, it is what I feel, the best set released in a LONG time.
As you may have noticed I have switched Tezzerator to straight and it has taken an entirely new form. We are working not only towards a stronger more consistent deck, but also a list that can hold itself up without Tezzeret, Agent of Bolas. Tap out has become a thing of the past, playing proactively is now something that is going to start putting us behind, switching to a control shell gives us reach, options and versatility. Looking at the list below you will see that there are now swords in the list, these have become a backbone for supporting our win conditions, which are seemingly weak, but when paired with various cards in the deck can become powerhouses on the turn of a dime.
I hope you enjoy the new list and as always feel free to ask questions and submit feedback
