Obviously drawn from the Season 2 finale of FiM. The card's info says: A Canterlot Wedding Normal Spell Activate only when you control "My Little Pony Princess Cadence" and "My Little Pony Shining Armor". Those monsters are unaffected by other card effects this turn and Battle Damage they inflict to your opponent becomes 0. If you control "My Little Pony Queen Chrysalis", that monster can attack your opponent directly this turn but detaches all of its Xyz Materials at the end of the Damage Step if it does. Common
