W/B Eldrazi is new to Modern; I call it Death and Taxes, but the archetype doesn't really have enough results to claim a name. The deck is similar to a hatebears deck but it does have an Eldrazi spin to it. The Eye of Ugin ban was far from enough to kill the Eldrazi menace and this deck makes use of Thought-Knot Seer and friends quite nicely.
The real payoff Eldrazi is Wasteland Strangler; there will almost always going to be a card of the opponents in exile to process. It was may seem weird to play four copies of Wasteland Strangler, a card that hasn't seen much Modern play, but there are actually a lot of early threats with toughness three or less that make it both removal and a creature that can be played on turn two. Blinking Wasteland Strangler with either Eldrazi Displacer or Flickerwisp is also huge value. Any creatures with enters the battlefield bonuses work wonders in this deck because of all the blink effects. Aether Vial's ability to put any creature into play at instant speed also is super relevant.
Against decks that want to search their libraries, the Leonin Arbiter / Aven Mindcensor package is well positioned. Even if the opponent is not playing search effects, they still make Ghost Quarter and Path to Exile much better. On occasion I have also seen people try to crack a fetchland without thinking and get severely punished, which is always amusing. This deck has a variety of ways of disrupting the opponent which gives it lots of game against pretty much any combo deck in Modern.
Even though I initially thought Aether Vial was one of the most important cards in the deck, I aggressively shaved them after sideboard. I think this makes sense; rather than taking out creatures, which are necessary in order to make Aether Vial good, you can just go ahead and take out some Aether Vials. This ensures you have enough business spells left in your deck along with the interactive sideboard cards.
The matches we played didn't come as all that much of a surprise. Other midrange decks are not easy to beat since your hatebears like Thalia, Guardian of Thraben and Leonin Arbiter are not quite as effective. Once our opponent got down an early Grim Lavamancer and Dark Confidant I knew we were in for an uphill battle.
The Death's Shadow deck isn't easy to play against but it seemed like once we knew their hand with a Tidehollow Sculler or Thought-Knot Seer it became possible to know exactly what we could afford to play around, which is a huge deal. As long as you can survive the first few turns without dying, that matchup seems pretty good.
When playing against Dredge I wasn't overly optimistic about the idea of winning a game without drawing graveyard hate, but it happened. Game two was quite interesting; normally Dredge is advantaged once it goes through most of the deck. Of course, some games versus Dredge can be blowouts, and while we got destroyed in the first game, it was definitely correct to mulligan to Rest in Peace in the final game.
