The tenth card is Mystical Fairy Elfuria, who looks to be more related to Spring than to Christmas. It lets you stop all XYZ summons other than those of the same level as a wind monster in your hand for a turn. The card seems to be connected to Ghost Fairy Elfobia, with similar names, levels, and their effects both looking at a wind monster you have in hand. If your opponent is running a XYZ heavy deck this might be helpful, but otherwise theirs not much for it do. Thank you Hill and Knowlton Strategies and Konami for letting us have this Advent Calendar.
