Cairngorgon, Antiluminescent Knight (MP15-EN030)

2 Level 4 monsters

During either player's turn, when another card or effect is activated that targets exactly 1 card on the field (and no other cards): You can detach 1 Xyz Material from this card, then target another card on the field that would be an appropriate target for that card/effect; that card/effect now targets the new target.
