An “attacking creature” is one that has been declared as an attacker or put onto the battlefield attacking during this combat. Unless that creature leaves combat, it continues to be an attacking creature through the end of combat step, even if the player it was attacking has left the game or the planeswalker it was attacking has left combat. Similarly, a “blocking creature” is one that has been declared as a blocker or put onto the battlefield blocking during this combat.
