If you would perform a listed effect while resolving an automatic ability of a J/ruler you control with "Caelth" in its name, instead add the following ng option option and then perform one; -"Perilous Potion" Search your deck for a dual-attribute wind/darkness Beast resonator card and put it into the field, then shuffle your deck. [Solo Mode] Banish this card: Put a dose counter on a J/ruler you control. Put the top card of your deck into your graveyard, then put a resonator card with total cost 2 or less from your graveyard into the field. You lose 500 life.
