Return a Pirate card from your graveyard to your hand, then do the same for Vampire, Dinosaur, and Merfolk.
When the battle is over, the bitterest foes at last find common ground.

Grim Captain’s Call doesn’t target the cards to return. You choose them while it’s resolving. No players may take actions between the time you make each choice and the time you return each card to your hand.

If you don’t have a card in your graveyard of one of the listed creature types, you just continue to the next listed type.

If a card in your graveyard has more than one of these types (such as a Dinosaur that’s a Vampire Dinosaur due to Arcane Adaptation’s effect), you may choose to return it for one of its types and return another card of the other type.

If an effect refers to a “subtype spell” or “subtype card,” it refers only to a spell or card that has that subtype. For example, March of the Drowned is a card that benefits Pirates and features Pirates in its illustration, but it isn’t a Pirate card.
