The Azorius Aggro deck appeared in one of the deck choices in the recently concluded Magic: the Gathering World Championships XXVII last weekend. This was piloted by the Japanese Pro Player Noriyuki Mori. Having to go through the Mono-White aims for consistency while splashing colors can make your deck become even more powerful.
Going for the deck build update, having Blue as the splash color for disruption and counterspells looks to be the better choice going to the current Standard format metagame. Their drawback though is that they aren’t much pressuring with only two to three power on the board, and they are vulnerable to burn and spot removals. I have seen the deck that is running out of gas against the Izzet control matchups when their draw is not consistent & which their initial assault is stopped.
I have found a similar decklist at the event posted named “Nationals 2021 Weekly Challenge @ Japan” where it finished in 2nd place. Check out the full decklist below.
