Creature â Human Pirate
Raid â€” Storm Fleet Aerialist enters the battlefield with a +1/+1 counter on it if you attacked with a creature this turn.
Raid abilities evaluate the entire turn to see if you attacked with a creature. That creature doesnâ€™t have to still be on the battlefield. Similarly, the player or planeswalker it attacked doesnâ€™t have to still be in the game or on the battlefield, respectively.
Raid abilities care only that you attacked with a creature. It doesnâ€™t matter how many creatures you attacked with, or which opponent or planeswalker controlled by an opponent those creatures attacked.
