Raid — When Timely Hordemate enters the battlefield, if you attacked with a creature this turn, return target creature card with converted mana cost 2 or less from your graveyard to the battlefield.
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.
