Simic Flash – M20’s Most Annoying Deck Yet!

Simic Flash – M20’s Most Annoying Deck Yet!

Simic Flash made a name for itself when Martin Juza used to reach Mythic this season on MTG Arena. Since then, it’s all over the ladder and people have been playing it non-stop. It’s consistent, it’s strong, and it’s hard to beat!

Simic Flash – Play Spells So Your Opponent Doesn’t

Simic Flash plays on two turns because you play on your own turn and have the ability to play on your opponent’s turns with its Flash creatures and its counterspells.

Not talking about this Flash!

The goal of the deck is simple. Control the tempo, drop your creatures, and keep them guessing.  

From Arena experience, I have never beaten a Simic Flash deck in a Bo3 match. It just ended up as a straight beatdown.

All Flash Creatures Here


Every creature on this deck has Flash, hence the name. If you’ve read my Mono Blue Upgrade article, you’ll find this deck shares the same creatures – Spectral Sailor, Merfolk Trickster, Brineborn Cutthroat.

Spectral Sailor is your only 1-drop and gives you something to do with your mana later on in the game.

Brineborn Cutthroat synergizes with everything on the deck because it just gets bigger the more spells you play on the opponent’s turn. And you know what happens when Brineborn Cutthroat is left unanswered.

Merfolk Trickster is a handy defensive creature at best that taps out certain creatures that are usually a pain in the rear end to deal with.

Frilled Mystic is a counterspell with a body that comes in during the later parts of the game. She’s really handy when you don’t have any counterspells in hand and they’re waiting to drop their biggest spells.

But the biggest threat in this deck is Nightpack Ambusher, a 4-mana 4/4 creature that gives your Wolves/Werewolves +1/+1. At the beginning of your end step, if you didn’t play any spell, it churns out a 2/2 Wolf Token.

Because you’re reserving your spells for your opponent’s turns, you’ll always end up generating 3/3 Wolf tokens.

Counter Spells Everywhere


This deck is equipped with 9 counterspells. 13 if you also count Frilled Mystics.

That’s more than enough to keep your opponents from playing their spells.

Syncopate and Sinister Sabotage are great for catching a lot of spells that Negate and Essence Scatter can’t.

Granted, Syncopate counters a spell unless the opponent pays X, so this comes in handy when opponents are forced to tap out their mana.

Sinister Sabotage counters any spells and allows you to filter through your library with its Surveil ability.

One Big Problem

Let’s address the elephant in the room.

The only time this deck doesn’t perform to its full potential is when a Teferi, Time Raveler is in play. Or when it’s about to drop and you have nothing to counter it with.

Its passive ability just prevents you from playing everything at Instant speed, including your creatures.

Check out MegaMogwai as he takes this deck for a spin on Arena:

The deck is one of the breakout decks in Standard right now, just right up there with Temur Elementals. And it’s seeing play on SCG Worcester happening this weekend!

If you want to get to Mythic in MTG Arena, this deck should help you do that.
