We’ve twice previously featured a Standard Eldrazi deck on Deck of the Day, but each Eldrazi color combination does something very differently. This version is B/G, and uses the powerful creatures found in B/G Constrictor to compliment the Eldrazi creature package. Despite sharing several cards with the B/G Constrictor deck, this B/G Eldrazi Constictor deck operates very differently.

The 3, 4, 5 Eldrazi punch we’ve talked about previously in Matter Reshaper, Thought-Knot Seer, and Reality Smasher is still the main core of this deck, but many of the holes in the mana curve are filled by the cards that black and green gives the deck access to. At 2 mana, which has historically been a weak spot for Eldrazi, Winding Constrictor, Scrapheap Scrounger, and the heavy flying beater Heart of Kiran are all fantastic, proactive plays at 2 mana. At the 3 mana slot, Catacomb Sifter is added as another creature that adds a good amount of power and toughness for its mana cost, and the additional value it gains can be a boon for this deck.


The other inclusion in this deck that’s worth discussing is Walking Ballista. You wouldn’t usually think that Ballista fits well into this Eldrazi deck that’s looking to play big, beefy creatures and beat down, but it’s an important role-player in this deck. It’s a good curve-filler, which is usually a big miss for Eldrazi, and it’s a good mana sink, which is most frequently the problem that Eldrazi decks run into. It also has very positive synergy with Winding Constrictor, which creates draws that closely resemble those from B/G Constrictor, which has the ability to run over decks with ease.

The sideboard plan indicates exactly what the deck wants to do against each of the format’s important decks. Natural Obsolescence is critical in this sideboard, as Heart of Kiran is a very potent threat against this deck due to its plethora of ground creatures. I think the sideboard is giving much too much credit to the B/G Constrictor deck’s viability in this format. B/G Constrictor appears to have few good matchups in this format, and its number will wane over the next few weeks.

Here are the changes I would make going forward:


-1 Catacomb Sifter

-1 Fatal Push

+2 Ruinous Path


-2 Lifecrafter’s Bestiary

-1 Tireless Tracker

+1 Fatal Push

+2 Kalitas, Traitor of Ghet

This is day 77 of Spellsnare.com’s 2017 Deck of the Day column, where each day we’ll feature a different Standard, Modern, or Legacy deck that caught our eye. You can read day 76 here, where we featured a Modern deck that aims for big mana, big creatures, and infinite mind control.
