# Relentless Assault Relentless Assault represents an interesting moment in Magic's design history as part of Portal Three Kingdoms, a set created specifically for the Asian market. The card offers a straightforward effect: extra combat phases for a reasonable mana cost. Collectors view it primarily through the lens of set completion, as Portal Three Kingdoms remains relatively scarce in Western collections due to its limited distribution. The card's mechanical simplicity makes it less sought after than flashier rares from the same set. Most interest comes from players building casual decks rather than serious collectors. The nonfoil-only status reflects the set's original printing constraints, which actually makes any Portal Three Kingdoms card somewhat notable for format enthusiasts tracking down regional variants.
