I need to see more context from the thread to understand what's being asked. Since I only have a partial mention, let me infer the most likely question: someone is asking about Prowess in a specific format. Let me pull data on Prowess across the most common formats it appears in.
The thread context is incomplete, but based on the mention and "I think prowess," this appears to be a discussion about what the best deck in Modern is right now. Here is what the data shows about Prowess in Modern over the last two months.
Prowess sits at 7th in meta presence at 3.64%, with 176 entries across 83 tournaments. Its winrate over that window is 48.6% (excluding mirrors), which puts it below the break-even line. The trend data paints a clearer picture: Prowess started January with a 47% winrate and has mostly hovered between 37% and 48% since, though it did spike to 59% in the final week of February on a smaller sample. That late uptick is worth watching but not yet conclusive given the low entry count that week.
For comparison, the format is currently dominated by Boros Energy (15.2% presence, 50.9% winrate), while overperforming decks include Ramp Eldrazi (54.6% WR), Blue Belcher (55.9% WR), and Affinity (52.4% WR). Prowess is a real deck with a solid core of Monastery Swiftspear, Dragon's Rage Channeler, Cori-Steel Cutter, and Lava Dart, but the numbers suggest it is not the format's best choice right now if you are optimizing for win equity.
