Mono-White has been a strong deck in Standard for quite some time. It suffered from the banning of Faceless Haven, but with a couple of great additions from Kamigawa: Neon Dynasty and Streets of New Capenna, the archetype has hardly slowed down.
Specifically, Mono-White has an impressive intersection of tournament results plus a very high win rate on Magic Arena. It consistently shows up in the top 8 of Magic Online’s Standard Challenges, and Untapped.GG shows it with a 58.2 percent win rate from Bronze to Mythic on the Best-of-Three ladder.
Mono-White is also one of the very best choices for Best-of-One play. It shows a 58.4 percent win rate on the Best-of-One ladder. Only one deck (Naya Humans) has higher at the time of writing.
