I wish the decks would stop adding cards that are for show. Like bruh, just put cards in that you "would" use depending on the situation. The standard deck, you got a Dark Palidin but no DM so you tell me exactly how you plan to summon him.
It's a situational card if you're facing a Dark Magician deck. Because Destruction Swordsman Fusion can use monsters from either side of the field as material.
^As said. Also there are some weird dark cavarly decks that use dark hex sealed fusion. In case you only have buster blader on hand dark paladin will be your only option.
