While I have other Orichalcos support cards written up, this one is the one I'm the most comfortable with sharing at the moment.   Orichalcos Soothsayer DARK/Lv 4/Psychic/Effect/0 ATK/1800 DEF While you control “The Seal of Orichalcos”, this card gains ATK equal to its DEF. While this card is in your field, GY or banishment, all of your “Orichalcos” monsters in your field, hand, Deck, GY or banishment are treated as Normal Monsters (but they still have their effects). You can discard this card from your hand; take 1 of  “The Seal of Orichalcos” that is in your hand, Deck, GY or banishment and place it face-up in your Field Spell Zone. You can only use this effect of “Orichalcos Soothsayer” once per turn.
