Yesterday, we featured Goryo’s Vengeance in Modern, so it only feels appropriate to keep the Through the Breach combo decks going. Today, however, we’ll be talking about the Mono-Red Sneak Attack deck in Legacy. This deck is centered around producing mana quickly, and using it on either Sneak Attack or Through the Breach. Those will then cheat into play powerful creatures like Griselbrand, Emrakul, the Aeons Torn, or Worldspine Wurm. Additional targets include Inferno Titan and Combustible Gearhulk (Kaladesh in the house!), but those are just as easily cast regularly from your hand.

Like many decks in Legacy that are trying to work with big mana, Chalice of the Void is in the deck as a playset to try to disrupt the opponent long enough that you can get your shenanigans online. However, unlike a lot of Chalice of the Void decks, this one also runs Trinisphere for additional disruption. It also plays Blood Moon as an additional form of disruption that attacks different strategies.

The true craziness in this deck comes in the sheer number of giant creatures it’s looking to sneak in. The moment most people fall in love with this deck is when they realize that Sneak Attack is not always a 1-off. Of the 16 creatures in this deck, 11 of them are good things to put in with Sneak Attack. Combustible Gearhulk is a particular highlight for me. It’s a lose-lose for the opponent, just how punisher mechanics should be. If any of the top 3 cards of your deck has another big fatty in it, the opponent will be taking damage. However, if it has 2 they simply die on the spot.

The sideboard has a lot of interesting cards in it. It has the 5th Blood Moon effect in Magus of the Moon, 2 copies of Pyrostatic Pillar to deal with Storm, a few copies of Sudden Shock to deal with pesky, small creatures, Defense Grid for extra protection, Chandra, Torch of Defiance as a repeatable source of card draw, a copy of Pyroclasm, and a card that is probably the most interesting sideboard card I’ve seen in a while, Pyromancy. For the uninitiated, which should be basically everyone, Pyromancy is a 4 mana enchantment that for 3 mana lets you discard a card and deal damage equal to its converted mana cost to target creature or player. The assumption I’m under is that it’s good against both Ensnaring Bridge and Humility at the same time, but it feels absurd to me that this card merits 2 sideboard slots. Logically, I’ll be leaving 2 copies there, as I know less about this deck than the player who piloted it, and they were clearly confident in this inclusion.

If you’re looking for a fast, linear, and definitely fun combo deck in Legacy, I highly recommend this one. It’ll pop up with a good result or two every now and again, and it always has the potential to beat almost every matchup it faces.

Here are the changes I would make going forward:


-1 Magus of the Moon

+1 Blood Moon


-2 Sudden Shock

-2 Shattering Spree

+4 Ingot Chewer

This is day 44 of’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 ready day 43 here, where we covered a Modern deck that can kill as early as turn 2!
