Copycat, which was deemed too powerful for Standard by just about every player, has had some amount of success in Modern, due in no small part to the absence of Splinter Twin. The two card combo (unfortunately in 3 colors) provides an interesting shell to build around, as neither are particularly strong on their own, but can put in some decent work against slower opponents.

The Copycat combo is made up of Felidar Guardian and Saheeli Rai, which when combined makes infinite copies of Guardian with haste. Feldiar Guardian has very little applications as a 1/4 for 4 mana, but it does have a nice interaction with Snapcaster Mage and Vendilion Clique, which caused this deck to go in the direction it has, as a more controlling midrange deck with a combo finish. Similarly, Saheeli Rai has the ability to filter through cards with her first ability, and play the grindy value-based game with Snapcaster Mage and Vendilion Clique as well.

In this sort of deck, Serum Visions, Path to Exile, and Remand are all more or less expected, but this deck has one or two more interesting options. A mainboard copy of Negate is more of a hedge against the removal spells that are likely to be pointed at Felidar Guardian, while Lightning Helix helps against the format’s aggressive decks that are looking to quickly reduce your life total. The more interesting inclusion in this deck is Spreading Seas, which can disrupt the opponent’s manabase very easily and replaces itself when it lands. Having the ability to disrupt the opponent helps this deck push its combo through, as opponents will need to be more concerned with casting their spells.


The black part of this deck adds quite a lot in the removal department. Fatal Push and Kolaghan’s Command are two of the most common and high-value removal spells in the format, and give this deck an extra edge when it comes to controlling the opponent’s board. Additionally, the powerful combination of Collective Brutality and Lingering Souls lets this deck play the long game better than almost all decks in the format.

Here are the changes I would make going forward:


-1 Negate

+1 Remand


-1 Disdainful Stroke

-1 Dispel

+2 Geist of Saint Traft

This is day 253 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 252 here, where we featured a Modern tokens deck that looks to go wide and grind the opponent out.
