DAT MOFOING COST (for both card and ability)
Indeed!
The card cost being high is kind of standard for all nymphs, but the ability is a rip-off in case of light nymph. E.g. Compare to dark: LS costs 4|3, but nymph ability costs only 2. While here its the opposite: Luciferin costs 2|1, but the nypmh ability is 4|3, WTF ???
IMHO, all the nymph ability costs should consistently match the spell costs of the corresponding alchemy cards.
