Today’s Magic: The Gathering Innistrad Crimson Vow Standard deck feature looks to check on the updated build of the Boros Aggro deck archetype. While the Mono-White version goes with the consistency in the mana-base, having access to Red is a minimal change with the lot of dual lands in the format for mana-fixing.
The deck maintains the strategy of just swarming with cheap casting creatures on their board and overwhelming opponents before reaching their sweep spells. Clarion Spirit and Usher of the Fallen generate free tokens pretty well, so you would commit less on your other creature spells and make them as the backup batch in case. Reckless Stormseeker grants haste which is relevant in dealing damage on idle turns where you cast your non-haste critters.
The late-game card draw of choice is still Showdown of the Skalds and also gives free +1/+1 to your dudes whenever you cast a spell in the next turns. Thalia, Guardian of Thraben, the new addtion to the White aggro lineup, is considered as a sideboard on this deck build. Maybe it is given that aggro was the dominant deck in the tournament.
The full decklist below was played by Steffen Berning in the Crokeyz Crimson Vow Tournament @ Team Liquid last Nov. 13th. He finished in the Top 16 of the event, out of 356 players.
