# Eel Umbra Eel Umbra is a straightforward common aura from Ultimate Masters that appeals primarily to limited players and casual builders. The card offers modest utility as an enchantment-based creature pump, fitting into blue-based strategies that value evasion and incremental advantages. Collectors generally view it as a bulk common with minimal demand outside of set completion purposes. The foil variant exists but carries little premium value, as Ultimate Masters foils remain relatively abundant in the secondary market. For most collectors, Eel Umbra represents the kind of filler card that rounds out set collections rather than a piece worth actively hunting or preserving.
