Repeating Barrage deals 3 damage to target creature or player.
Raid — {3}{R}{R}: Return Repeating Barrage from your graveyard to your hand. Activate this ability only if you attacked with a creature this turn.

Raid abilities care only that you attacked with a creature. It doesn’t matter how many creatures you attacked with, or which opponent or planeswalker controlled by an opponent those creatures attacked.

Raid abilities evaluate the entire turn to see if you attacked with a creature. That creature doesn’t have to still be on the battlefield. Similarly, the player or planeswalker it attacked doesn’t have to still be in the game or on the battlefield, respectively.
