# Splitting Headache Splitting Headache is a common from Shadowmoor that represents a straightforward damage effect with a split-second mechanic. Collectors typically view it as a functional utility card rather than a standout piece, though it holds modest appeal for players building around the split-second mechanic or red-based limited decks from that era. The card exists in both nonfoil and foil versions, with foils being the more sought variant among collectors who prioritize condition and visual presentation. Neither version commands significant collector attention, making Splitting Headache primarily relevant to set completionists or players nostalgic for Shadowmoor's mechanical identity rather than serious investment pieces.
