One of the ways to keep in touch with the Standard metagame is to check on the tournament results from various weekly major events. I have found this website that covers the metagame when the weekly results are published at the Magic Arena site. This specific post covered the dates October 12th when the Omnath, Clover, and Escape were banned, up until October 18th. This is for the Standard BO3 Week 5 metagame, and the Top 5 archetypes are as follows:

1. Rakdos Midrange (64.90% Non Mirror % Win Rate)
2. Dimir Rogues (50% Non Mirror % Win Rate)
3. Mono-Red Aggro (64.90% Non Mirror % Win Rate)
4. Gruul Adventures (39.30% Non Mirror % Win Rate)
5. Mono-Green Aggro (36% Non Mirror % Win Rate)

You can check the complete details of the report on the link here.

It was the first week of the recent bannings that were implemented and so that is what’s left of the other decks’ archetype in the meta. They are adjusting with an empty hole that the elephant in the room has left and so the development and updating might take a while. Anywho, we would expect the rise in statistics of new decks as they would become a popular choice among players. We will see if this will be reflected in the coming weeks.
