# Reality Acid Reality Acid is a common from Planar Chaos that appeals to collectors interested in enchantment-based removal and time-shifted designs. The card's unique mechanic—exiling a permanent with a delayed trigger—made it notable for limited play and casual formats. Collectors appreciate it as part of Planar Chaos's experimental design philosophy, which revisited mechanics in new colors. The foil variant holds modest collector interest, as foils from this era can show aging and curl issues. Most collectors view Reality Acid as a functional common rather than a chase piece, though it remains relevant to those building comprehensive Planar Chaos sets or exploring the set's mechanical innovations.
