Lunatite - Parasite Métallisant DCR-FR074

Once per turn, during your Main Phase, if you control this monster on the Field, you can equip it on a face-up monster on your Field as an Equip Spell Card OR make it a monster, in Attack Position face-up. When this monster is equipped on a monster due to its effect, the equipped monster will not be affected by the effects of any Spell Card controlled by your opponent (1 monster can only be equipped with 1 Union Monster at a time. If the monster equipped with this card is destroyed in battle, destroy this card instead)
