BO1 Mono Blue Devotion for Theros Beyond Death Standard

I hope you like the deck, feel free to upvote the list or comment if you have any suggestions!

Welcome to my first competitive build for the new Theros Beyond Death standard season. I think the Mono-Blue archetype is positioned to preform very well in relation to the other popular options in the meta. The massive flying creatures that blue provides can really establish a board presence early against decks such as Gruul and Rakdos aggro variants, and the tempo this deck leverages through the key new card Thassa, Deep-Dwelling should make mono-blue a solid midrange option.

Thassa, Deep-Dwelling

Thassa, Deep-Dwelling is the key new piece introduced to this strategy that I think pushes mono-blue to the top of the competitive meta. Her ability to blink a creature every turn (especially on the turn you play her) allows us to abuse ETB triggers, in which there are plenty powerful options in blue.

• Thassa's Oracle
• Emry, Lurker of the Loch
• Cavalier of Gales

• Agent of Treachery

• Thassa's Oracle lets us set up our draw in the early game, provides important devotion for Thassa, Deep-Dwelling , and provides an alternate way to win in a very gummed-up board state. The ability to blink this every end step is amazing, and is the perfect 2 drop for the deck. A budget alternative for paper would be to run Fblthp, the Lost , or for Arena if you already have the copies.

• Emry, Lurker of the Loch is an alternate form of card draw that allows us to recycle cards like Vantress Gargoyle or Witching Well if they hit the graveyard. Additionally, blinking her with Thassa, Deep-Dwelling mills 4 every end step, making Thassa's Oracle a more realistic 2nd option to win. In this quick of a format, I wanted to make sure I have early turn plays, and this deck curves nicely with a T1 Witching Well into T2 Emry, Lurker of the Loch .

• Cavalier of Gales is an all-star target for Thassa, Deep-Dwelling , as you get a free Brainstorm every end step. Additionally, this interaction allows the Cavalier of Gales to attack with pseudo-vigilance, as it will be blinked and return un-tapped on the end-step so that it can block. The curve of T4 Thassa, Deep-Dwelling into T5 Cavalier of Gales will be back-breaking for any deck that cannot interact at instant speed, given you will only need one more in order to turn Thassa, Deep-Dwelling into a creature for attacking.

• Agent of Treachery is included in the deck as a powerful late-game finisher. The mana required for Agent of Treachery can be produced through Nyx Lotus , as well as ramp provided by Kiora, Behemoth Beckoner . If you are able to cast Agent of Treachery with a Thassa, Deep-Dwelling on board, you will effectively be stealing 2 permanents for the price of 1. Any more end steps after the 1st with this combo will be too much for the opponent to deal with, as you will be drawing 3 cards and stealing a new permanent every end step.

Card Draw

Card draw in this deck comes in a variety of different ways, mainly through use of Kiora, Behemoth Beckoner during the mid-game as a bonus to playing large creatures, the ETB effect of Cavalier of Gales , and Gadwick, the Wizened as a curve topper to refill your hand towards the late game. When paired with the recursion Emry, Lurker of the Loch provides, along with scry effects from Witching Well and Thassa's Oracle , this deck is able to pretty easily manipulate its library.

Interaction

The weakness of this deck as a BO1 build is interaction/removal. That being said, I think the only real weakness this deck faces is against a hard control build, such as any flash, or control decks. There is plenty of board presence in the early game in terms of blockers like Vantress Gargoyle and Thassa's Oracle , as well as a few more directly interactive cards in the form of Brazen Borrower , Gadwick, the Wizened , and Agent of Treachery .
