This week we present a deck analysis and sideboard guide for Eldrazi Aggro (often called Eldrazi Stompy or Colorless Stompy), a deck that aims to "cheat" on the mana curve to cast huge threats much earlier than expected. Let's start by looking at the deck:
This list represents the most recent and aggressive evolution of Eldrazi in Modern, transformed by the new additions from Modern Horizons 3 into a war machine capable of generating suffocating pressure from the very first turns of the game. The deck abandons the relative slowness of Tron variants to embrace a "Stompy" philosophy, where the main goal is to "cheat" on the mana curve to cast oversized creatures before the opponent can stabilize their strategy. Let's look at the fundamental concepts of the deck's core and then move on to the sideboard.
Mana and Acceleration
The true beating heart of the deck lies in its ability to manipulate mana production through Ugin's Labyrinth and Eldrazi Temple. The Labyrinth, in particular, finds its perfect partner in Devourer of Destiny: by exiling the Devourer via its Imprint ability, you get a land that produces two colorless mana from the first turn. This allows for explosive plays that would normally take three or four turns to complete. In addition to serving as fuel, the Devourer acts as a powerful filter for the deck during the initial setup phase, ensuring a consistency that older colorless versions struggled to find.
Offensive Pressure and Synergies
The speed of the offensive is guaranteed by new pieces like Glaring Fleshraker and It That Heralds the End, which act as true "lords" for your colorless creatures. The Fleshraker is particularly dangerous because it transforms every spell cast into incremental damage and resource advantage, generating Scion tokens that can be sacrificed for additional mana. The finishing blow is often delivered by Eldrazi Linebreaker, a fast threat that can shift the momentum of the game in a single attack. Sowing Mycospawn is also fundamental, a card that not only accelerates your mana base by searching for key lands like Cavern of Souls but simultaneously sabotages the enemy's game plan by exiling their most precious lands.
Control and Disruption Elements
Despite its aggressive nature, the list includes disruptive control elements that make life difficult for many decks in the current meta. Chalice of the Void remains a mandatory choice for shutting down decks based on one-cost spells, while Thought-Knot Seer continues to be the best tool for removing specific threats directly from the opponent's hand while providing a solid body on the field. Kozilek's Command closes the circle by offering total versatility: it can remove annoying creatures, empty graveyards against combo strategies, or simply draw cards to maintain pressure in the late game.
Sideboard and Match-ups
The strength of this list lies in its resilience to counterspells thanks to Cavern of Souls and its ability to bypass opponent's defenses with imposing creatures like Sire of Seven Deaths. However, the deck can suffer from excessively heavy draws lacking accelerators or specific hate cards like Blood Moon, which can completely paralyze the non-basic mana base. The sideboard has been structured to address these criticalities, with Trinisphere ready to punish faster, "spellslinger" decks, while All Is Dust acts as a definitive reset button against any deck based on colored permanents.
Boros Energy
Note: Do not keep hands without interaction or slow hands. Otherwise, you risk dying to their explosive starts that you won't be able to handle. Look for hands with Eldrazi Temple and Thought-Knot Seer — they are gold. Avoid hands full of slow pieces because in most cases you will die or lose control too early.
The strongest play you can make, of course, is Chalice of the Void for X=1 on the play. Be careful doing it on the draw, though, because a connecting Ragavan bringing the opponent to 3 mana can become unmanageable even if you played Chalice at 1. Carefully evaluate the risks of each play, and if the opponent has a strong start, accept it: it's a Tier 1 deck for a reason.
Sire of Seven Deaths with Chalice at 1 is almost always a guaranteed win. In general, it's an extremely strong card in the matchup, and if it gets trapped under Static Prison, remember you have Wastescape Battlemage to exile the prison. Watch out for Phlage, Titan of Fire’s Fury.
IN: 3 Dismember, 2 All Is Dust, 1 Wastescape Battlemage OUT: 2 Sire of Seven Deaths , 4 Mycospawn
Izzet Prowess
Note: looking for hands with interaction is key in this matchup — along with respecting it and not underestimating it. Remember: even if you're at 20 life, you can still die. Respect the matchup.
Chalice of the Void for X=1 on the play is a win condition. Cards like Kozilek’s Command and Thought-Knot Seer are extremely powerful.
Sire of Seven Deaths — if you manage to resolve it and you're not already dead — could easily offer you an ice cream along with the victory.
Try to manage the timing of Wastescape Battlemage against Coresteel Cutter well, and carefully evaluate whether to play Chalice at 1 or 0 based on how the opponent starts the game — especially if you suspect they want to activate Coresteel Cutter with Bauble and generate value that way.
IN: 3 Trinisphere, 2 Wastescape Battlemage, 2 All Is Dust OUT: 2 Sire of Seven Deaths , 4 Mycospawn, 1 Fleshraker
Orzhov Blink
Note: looking for hands with interaction is correct. Their strongest play will always be the Phelia, Exuberant Shepherd + Overlord combo. If you have removal you can be a bit calmer, otherwise if the combo resolves you are already at a disadvantage.
We still have the emergency button called All Is Dust, which acts as a lifeboat if the situation gets out of hand.
Sire of Seven Deaths is extremely strong here. Either they deal with it, or they will die slowly.
IN: 3 Dismember, 2 All Is Dust OUT: 4 Chalice of the Void, 1 Sire of Seven Deaths
Eldrazi Ramp
Note: not much to say. Whoever starts land hate first usually wins. It's not much fun, but it's very fast.
Hands with Mycospawn and Wastescape Battlemage can be gold in some situations, because they allow you to destroy Utopia Sprawl and the talismans, slowing them down so you can start land hate earlier.
(Of course, once you start destroying their lands you have to apply pressure — otherwise, if they manage to cast Emrakul for 13, it won't end well... but I guess you know that.)
IN: 2 Relic of Progenitus, 2 Wastescape Battlemage, 1 Dismember OUT: 4 Chalice of the Void, 1 Sire of Seven Deaths
Dimir
Note: DO NOT DIE TO Harbinger of the Seas. Play around the card and respect it.
This deck DIES to that kind of land hate, so look for Cavern of Souls and always keep their turn 3 in mind, when they might play it.
Don't be caught off guard.
IN: 2 Relic of Progenitus, 3 Dismember OUT: 2 Sire of Seven Deaths , 1 Linebreaker, 2 Wastescape Battlemage
Amulet Titan
Note: speed and disruption — that's the key.
They are fast and can kill you easily. If you can hinder them with Wastescape Battlemage on Saga, Amulets, or Spelunking while applying pressure, you win. Otherwise, mulligan.
Don't keep mediocre hands — you might as well go for a smoke or a Coke, because you'll lose that game anyway.
IN: 3 The Stone Brain, 2 Wastescape Battlemage OUT: 2 Sire of Seven Deaths , 1 [card]Glaring Fleshraker [/card] , 2 Mycospawn
Belcher
Note: you need to be fast and have hate pieces. There's not much else to say.
IN: 3 The Stone Brain, 1 Wastescape Battlemage OUT: 2 Sire of Seven Deaths , 1 Devourer, 1 Sire of Seven Deaths
Neoform
Note: pray.
IN: 3 The Stone Brain, 2 Wastescape Battlemage OUT: 4 Chalice of the Void, 1 Sire of Seven Deaths
Domain Zoo
Note: you need hands with interaction. If they start with Leyline and Draco and you don't have Wastescape Battlemage, you've pretty much already lost because you won't be able to respond. If they start with Ragavan and Kavu and you don't have interaction, you're already behind.
This is a battle of Magic — you need hands with interaction and key pieces. The first one to run out of answers loses.
Remember you have Sire of Seven Deaths. If they hit it with Leyline Binding, you have Wastescape Battlemage.
Respect Consign to Memory, which even if it doesn't counter creatures with Cavern of Souls, it counters triggers like those of Wastescape Battlemage or Thought-Knot Seer, as well as spells like Kozilek’s Command.
Use your cards sparingly.
IN: 3 Dismember, 2 Wastescape Battlemage, 2 All Is Dust OUT: 2 Sire of Seven Deaths , 4 Chalice of the Void, 1 Fleshraker
Ruby Storm
Note: without hate here, as against Amulet Titan, you will simply lose. Do not keep mediocre hands or hands without hate hoping the opponent will lose on their own. It won't happen in most cases.
IN: 3 Dismember, 2 Relic of Progenitus, 3 Trinisphere OUT: 2 Sire of Seven Deaths , 2 [card]Glaring Fleshraker [/card] , 4 Mycospawn
Broodscale Combo
Note: keep hands with interaction for their combo. It's not hard — you just need to know when to interact. I don't consider it a complicated matchup, but pay attention and respect their combo turns.
IN: 3 Dismember, 2 Wastescape Battlemage OUT: 4 Sire of Seven Deaths , 1 Chalice of the Void
