Rulings and Errata
The Feayn will likely be given the elf (type) keyword when AEG releases errata for Classic Thunderstone, but currently it is not an elf. However, there are currently no cards that trigger off the elf keyword, so that's okay. Additionally, the Sniper's Spoils effect does not currently trigger off of Rank 4 in the Wilderness side of the board in Thunderstone Advance.
