It’s been a while since we’ve curved Cloudfin Raptor into Frostburn Weird into Thassa into Master of Waves. While this deck doesn’t have the power level that deck did, it’s still strong. When you factor in that the entire deck can be purchased for a few dollars, this is definitely one to be prepared for at FNM!
Tempest Djinn puts mono-blue aggro strategies on the map. A 3/4 flying creature for 3 mana is already insane. Serendib Efreet is one of the best creatures ever printed, and this doesn’t have the drawback. In fact, it gets better every turn. Drawing this later in the game just means you’re getting a cheap 7/4 flying creature, and that’s something we can all get behind.
You’re looking to get your beats on early and Siren Stormtamer does exactly that. A cheap flying creature is already exactly what this deck wants, but being able to protect the bigger threats is also a massive upside.
Warkite Marauder gives you another cheap evasive threat that can get in for multiple damage each turn. You can’t do much to take advantage of its attack triggers, but you can disable your opponent’s flying blockers.
Storm Fleet Aerialist keeps up the beats as another cheap flying threat to put the opponent on the back foot.
Nimble Obstructionist gives you a few options. You can cycle it for a card and counter an important ability (like a planeswalker ultimate or something else that could really hurt you), or you can flash it in as a 3-power, 3-mana flyer. Both of these options are strong, and this is a great addition to the deck.
Dreamcaller is the top of your curve and gives you yet another flash, flying threat. You’ve got a lot of Pirates in this deck, so the Siren’s ability should be active frequently. Tapping down a pair of the opponent’s nonlands means it’s easier to win races by hitting attackers or blockers.
Favorable Winds is a 2-mana anthem in this deck—every single creature happens to have flying. With it, you get an enchantment that’s hard to interact with and pumps your entire team for the duration of the game.
Curious Obsession does serious work in this deck. It’s a single mana, so you rarely lose tempo, and it’ll immediately deal an extra point of damage and replace itself. A single hit means that you don’t mind your creature dying, but if it lives, you should run away with the game. You already have Stormtamer to help protect whatever is curious, but you also have some countermagic.
Lookout’s Dispersal is just a turbo Mana Leak in a deck like this. You have lots of Pirates, so it should almost always cost 2, and when it doesn’t you were probably losing anyway since you don’t have any threats in play! This makes it very hard to interact with your curiously obsessed threats.
Unsummon isn’t a powerhouse, but this deck doesn’t need any power. You’re looking for tempo to win the game before power matters. Unsummon can stop an attacker or blocker, but you’ll also use it to protect one of your own creatures from removal. That’s a loss of tempo, but when you’re “countering” a Vraska’s Contempt and putting multiple threats on the table again, things still work out nicely.
Mono-Blue Aggro is one of the cheapest decks Standard has seen in some time, and having a competitive option that anyone can pick up is awesome!
