Rockslide Ambush Price

Updated 2026-09-03

Rockslide Ambush is a red instant from Portal Three Kingdoms, one of Magic's rarest and most collectible sets from 1999. The Portal Three Kingdoms set was distributed primarily in Asian markets with limited North American availability, making authentic copies scarce on western secondary markets. The card itself is a functional combat trick, but its value is almost entirely driven by Portal Three Kingdoms provenance and the scarcity of the print run. Near-mint copies are priced around thirty-eight dollars, up roughly one percent over the past month but more than fifty percent over the trailing quarter. That dramatic ninety-day appreciation against flat recent movement suggests a price consolidation following a significant run-up, possibly driven by collector demand or a buyout event. Portal Three Kingdoms commons and uncommons have seen sustained appreciation as collectors pursue complete sets. With supply inherently limited by the original distribution geography, the upside case for continued appreciation over the long term remains credible.
