Guilds of Ravnica has officially been released and the citizens of Magic Online wasted no time building decks and winning Treasure Chests with Magic's newest set. I check the Magic Online decklist publications often, and they're an excellent source of tech for upcoming tournaments. People sometimes refer to the players of Magic Online as the hive mind, and in a way, they are; they're nameless and faceless Spikes who only care about winning, which shows through in their decklists.
When reviewing the latest decklist dump, the first deck I saw which looked obviously powerful is Mono-Red Aggro. It's no secret that Goblin Chainwhirler is a sick card and any deck that can give it a home is already inherently advantaged, but Mono-Red Aggro has a new look thanks to Runaway Steam-Kin.
We're entering a Standard format which only contains five sets: Ixalan, Rivals of Ixalan, Dominaria, Core Set 2019, and Guilds of Ravnica. This is significant for a few reasons, but the biggest one for me is that the card pool is smaller than usual and thus aggressive strategies benefit the most. Week 1 of Standard, beatdown decks overperform, since the decks you play against are less likely to be tuned or consistent.
Therefore, I highly recommend this updated version of Mono-Red Aggro for a Week 1 metagame. This version has more burn than we've seen in the past and I love it. Fanatical Firebrand may look like "just another one-drop," but if you can reach the final chapter of The Flame of Keld, it's a walking Lightning Bolt. Viashino Pyromancer behaves similarly.
