Gamea still hasn't update this card, even though the official website has clearly shown that DL uses the latest errata (that changes the effect into non-targeting) XD

Oh, so that' why it works against Slash Dragons. I'm running a Darklord deck with three Rykos and I found weird being able to destroy them when they had a warrior equipped. Doesn't make much sense since you're literally targeting a card, but ok.
