I'll analyze the current Standard metagame post-Vivi ban to see what the data shows about diversity and URx deck prevalence.
Now let me calculate the combined URx presence and get sources:
The data shows Standard has genuine diversity post-Vivi ban, not 63.5% URx decks. Across 53 tournaments in November, URx archetypes (Izzet Cauldron, Izzet Looting, Izzet Prowess, Jeskai Control) combine for 21.84% of the metagame - strong but far from dominant. The top archetype is Izzet Cauldron at 15.02% presence with a 56.03% winrate, followed by Dimir Midrange at 12.55% and Mono Red Aggro at 11.66%. Eight distinct archetypes hold at least 2% of the meta.
Worlds represents a small, high-stakes sample where players gravitate toward perceived best decks, amplifying URx representation. The broader tournament data reveals healthy variety: Dimir Midrange, Mono Red, Simic Midrange, Reanimator, and Bant Airbending Combo all posting real results. While URx shells are clearly tier 1, they face competitive opposition from multiple strategies.
The format appears balanced with Izzet Cauldron as a clear frontrunner but no single oppressive force. The 63.5% claim likely reflects Worlds specifically, not the actual competitive landscape where three out of every four decks are playing something other than URx.
