Raid —
: Return Repeating Barrage from your graveyard to your hand. Activate this ability only if you attacked with a creature this turn.Card Rulings
1/19/2018 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.
1/19/2018 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.
Obviously having to attack to get the option to bring it back is an issue (though raid is just attacking not actually hitting), but you get so much more info when you see what you'll draw, if your opponent has any tricks during combat etc.
It's Hammer time.
