There have always been different viable builds of Eldrazi Ramp. I had been playing a GR version on Magic Online. I was winning over 80% of my matches in Leagues, but got decimated in the MOCS. Some of that was due to bad draws, some due to other players being more prepared. The Bant Company deck, which on the surface seems like a good matchup for Eldrazi, is actually not as weak to cards like Kozilek’s Return thanks to the many 3-toughness creatures. If more decks don’t care about the powerful mythic, maybe red isn’t necessary?
Simon Nielsen managed to pilot his Mono-Green Eldrazi Ramp deck into the finals of the MOCS Quarterly Event this weekend, qualifying him for the Championship. Forgoing red entirely means no Kozilek’s Return, but enables the most consistent ramp in the format: Rattleclaw Mystic, Whisperer of the Wilds, and even Hedron Crawler. My theory was that it was better to omit these cards and make opposing Fiery Impulse and Ultimate Prices dead cards, but that didn’t end up being the case this weekend.
With 9 mana creatures at 2 mana, the ability to ramp to 4 is consistent in this deck. Adding to that consistency of both having the lands or the mana creatures is Hedron Archive. Not the most powerful card, but for a deck that doesn’t feature much in the way of card draw, adding to the consistency to power out the big draws is huge. With 16 cards you can miss with an Oath—assuming you have a green mana and an Oath itself, you have 15 misses in “58 cards” which translates to about a 2% chance of missing entirely with the Oath.
Once you have a mana creature and 3 lands, the options at 4 are tremendously powerful. Hedron Archive is one of the best things you can be doing, ramping and providing potential card advantage later on. Playing Whisperer of the Wilds into Hedron Archive in a field full of Kolaghan’s Commands is what scared me off of playing a version like this but when that doesn’t happen, you are going to dominate. Explosive Vegetation is the best ramp spell in Standard, fixing your colors (even if that just means colorless from Wastes to go with your Mono-Green deck), and getting you up to 7 mana as early as turn 4. Without a 4-mana ramp spell, of which you have 8, Thought-Knot Seer can come down and disrupt the opponent. If you do get straight up to 7 mana, that’s when World Breakers start breaking worlds.
Hedron Crawler is a sweet addition to the deck, helping to provide early colorless for Thought-Knot Seer and also being immune to Ugin, the Spirit Dragon’s minus ability. The other big Oath of the Gatewatch addition to the deck is having access to Spatial Contortion in the sideboard, meaning you can sideboard in early removal against aggressive decks, just like many of the other control decks who board in Ultimate Price.
