Caw Gates leans on Melded Moxite as a key artifact engine piece, so Dust to Dust gives us a way to strip it away along with any other artifacts. Loyal Sentry is a fine cheap blocker against their small aggressive creatures like Sacred Cat and Outlaw Medic. Skred remains solid removal for their small white/red creatures. Dispel, Ride's End, and Fanged Flames are trimmed since Ride's End is too slow against this proactive aggro-midrange plan and Dispel is too narrow, especially since they can rebuy answers with Prismatic Strands' flashback.
