We’ve previously featured a more traditional Sneak & Show deck on Deck of the Day, and today we’ll be looking at a variant of the powerful 2-card combo deck, Eureka & Show. Where Sneak & Show uses red for Sneak Attack (and sometimes Through the Breach), Eureka & Show uses green for Eureka and powerful sideboard options.

Most of the individual card decisions made when building Eureka & Show versus Sneak & Show come directly from the differences found between Eureka and Sneak Attack. Sneak Attack can only put creatures into play, while Eureka can put any permanent into play. Because of this, Omniscience is a much more viable option for this version of the deck. Eureka also allows you to put multiple big scary monsters from your hand into play in one go, which further incentivizes you to stuff more payoff cards into your deck.

Intuition is a card that remarkably sees play “sometimes” in several different decks. At its core it is a 3 mana Demonic Tutor at instant speed. You may notice a lot of 3’s in this decklist, and that’s not a coincidence. The vast increase in power when 2 copies moves to 3 in an Intuition deck is an important thing to take advantage of. 3 copies each of Emrakul, the Aeons Torn, Griselbrand, and Omniscience are included in those numbers to take advantage of it. This sort of effect is better in this version of this deck due to the slightly slower nature of Eureka when compared to Sneak Attack.

The sideboard of this deck has a lot going on, but I think that it’s not built correctly. As I just mentioned, Intuition‘s effect as Demonic Tutor is only an option when you have access to 3 copies of a card in your deck. Krosan Grip and Echoing Truth are exactly the type of cards that you want to be able to search out from your deck, and should both have another copy moving forward. Carpet of Flowers is another powerful inclusion in the sideboard of this deck. Its mana production against the format’s blue midrange decks and Miracles is unparalleled, and the extra mana is significantly more relevant in a combo deck like this one than one might think.

Here are the changes I would make going forward:


-1 Preordain

+1 Intuition


-1 Boseiju, Who Shelters All

-2 Flusterstorm

-1 Leyline of Sanctity

+1 Krosan Grip

+1 Echoing Truth

+2 Grafdigger’s Cage

This is day 109 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 read day 108 here, where we featured what many consider to be the absolute grindiest deck in Modern.
