Arcane Fortress Synergy Inner Sleeves in phantom purple are made for players who want to add personality to a deck without sacrificing tournament legality. These inner sleeves feature a colored front border that helps cover older or mismatched card frames while staying hidden from the back when used inside opaque outer sleeves. They're perfect for double-sleeving, tuning deck aesthetics, or giving a favorite build a cleaner, more unified look without changing the card itself. If you enjoy customizing presentation as much as gameplay, these Synergy Inner Sleeves are an easy way to add color, polish, and extra protection at the same time.
