I can see a deck list but no explicit question was included in the mention. Let me identify the archetype first, then pull relevant data.
The list is clearly Cascadia (also known as Temur or 4/5-color Rhinos) built around Crashing Footfalls + Violent Outburst/Shardless Agent, with Leyline of the Guild-Pact enabling Leyline Binding as free removal and Scion of Draco as a threat. Let me look up current Modern data for this archetype.
Good, found it as "Footfalls" in Modern. Let me now get detailed data on this archetype.
Here is what the data shows on your Footfalls build in Modern.
The archetype is struggling right now. Over the past two months, Footfalls posted only a 40.4% non-mirror winrate across 104 matches, placing it well outside the competitive tier in a meta currently dominated by Boros Energy (13.75% share, 51.3% WR), Affinity (9.1%, 52.5%), and Broodscale (54% WR). Presence has also been razor-thin, peaking at just 2.84% in mid-May and then trending downward to under 0.5% most recently.
Looking at your specific list versus the tournament field, several notable divergences stand out. The consensus 75 leans heavily on Subtlety (100% presence, avg 3.86 copies) as the primary free pitch threat, but your list omits it entirely, replacing it with Scion of Draco and Leyline of the Guild-Pact. Leyline Binding appears in your list as removal, but it does not show up as a tournament staple in the tracked Footfalls lists, which instead rely almost universally on Dead // Gone (85.7% presence, avg 3.07 copies) and Fire // Ice. Quantum Riddler (82.9%) and Endurance (60%) both appear in your list and are well-supported by the data as flex threats. Your sideboard choices also align well: Mystical Dispute is in 100% of tracked sideboards, and Endurance in 91.4%, while Teferi, Time Raveler is a fringe option at only 5.7% sideboard presence.
The Scion of Draco + Leyline of the Guild-Pact package appears to be a personal innovation. It is not reflected in the current tournament builds, which suggests either it is underexplored or the community has already rejected it. Given that the archetype as a whole is underperforming at 40%, this list is swimming upstream in the current meta.
