After an exhaustively bad showing at GP Vancouver 2017, I have decide to change a few things around from the list. Not only did a Mono-White E&T list make the top 8 of the event it was so drastically different from my own I started to really see where I went wrong. in an effort to beat a lot of not so popular decks I lost to the rest of the field.
I found that my Spirit of the Labyrinth + Geier Reach Sanitarium Lock was just a little too cute to be worth the 3 card slots.
Too many decks have main deck wrath spells. and Blood Moon is almost an auto-win against me. Both rounds that I played against blood moon decks I lost to my own mana base. so in an effort to combat both of those things I will be substituting my Spirits and Sanitarium for Selfless Spirit and a single Wastes. it will give me main deck protection from wrath/spot removal as well as a 5th fetchable source from Path to Exile and Ghost Quarter. Also of note, Spirit of the Labyrinth was great against the blue decks and made combat with Thought-Knot Seer a lot easier it just so happened to be an easily killed enchantment creature. Normally that isn't an issue, but with B/G/x match ups they don't really "Draw" extra cards and the Enchantment type in the GY mattered for Tarmogoyf.
A few things that went right, were the Fatal Push, Fragmentize, and Cataclysm Gearhulk. all of which performed remarkably well against the decks I needed them against.
I will try and update here with my findings when I can. but it will also be a while before I can play anything larger than FNM.
