Relentless Assault Price

Updated 2026-08-22

Relentless Assault from Portal Three Kingdoms is a rare combat step enabler that allows its controller to have an additional attack phase after the first. The card's significance derives almost entirely from its set: Portal Three Kingdoms was printed in limited quantities and sold primarily in East Asian markets, making it one of the scarcest competitive-card sources in Magic's history. Many Portal Three Kingdoms cards were initially illegal in tournament play due to the set's simplified card template, a restriction eventually lifted. The combination of a useful combat effect and genuine collector scarcity drives the price well above what the effect alone would command. Price action over the measured window has been flat, consistent with the illiquid nature of Portal Three Kingdoms cards: transactions are infrequent, and the collector base for this specific set is specialized. Condition is the primary price variable for any Portal Three Kingdoms card.
