Modern: Nadu combo forces format volatility.

Modern’s Final Health Index lands at a solid 66.1 this week, signaling that while the format is generally stable, players are navigating an intense period of flux. The B&R Health Score sitting high at 80.0 suggests that the structural integrity of the format remains strong, even if the metagame feels entirely upside down following recent releases. This stability is critical, especially since the recent B&R analysis confirmed no specific card changes are imminent, expecting the format to self-correct.

Looking closer at the metrics, the Metagame Diversity Score of 71.7 and the outstanding Archetype Distribution Score of 92.3 confirm that a wide variety of strategies remain competitively viable. However, participation is a real concern; while MTGO is showing slight growth (1.6% monthly), Paper participation is declining precipitously at an average of -24.7% per month. This decline is pulling the overall Player Growth Score down to 45.3, indicating that engagement, especially in person, is struggling.

The battle for the top spot is intensely tight right now. UR Aggro and Death And Taxes are sharing the lead, both claiming 10% of the reported metagame share, with Affinity trailing closely at 9%. The overall breakdown shows Aggro strategies dominating at 46.7% of the super-archetype share, just ahead of Combo at 37.6%. If you aren’t running something fast, you are likely losing speed to the field.

The community discussion confirms this rapid shift, characterizing the format as "volatile" post-*Modern Horizons 3*. The primary subject is the relentless efficiency of the "Nadu Combo decks." Strategies utilizing *Nadu, Winged Wisdom* alongside zero-cost equipment like *Shuko* or *Slippery Bogle* are dictating the pace of play and generating widespread calls for action. Elsewhere, the *Flare* cycle is seeing significant adoption, with *Flare of Denial* proving instrumental in blue strategies. Players are also refining new Eldrazi lists and experimenting with *Wrenn and Realmbreaker* in midrange shells, showing that adaptation is currently the required mode of survival.
