Event-themed REM are usually just filled with color-swapping event-themed art card but as this timing coincides with the new type-killer and co-op awakenings, this REM provides a way for "early access" to those awakenings. 

The worst card is probably NYTengu. The only changes from the original Tengu was the sub-color which hardly mattered and the LS probably isn't good enough anyway. A more useful AS or more awakenings would have been so much better. Therefore, I think you are basically spending 5 stones for a NY themed-art of a descend-farmable boss.
