It sounds like you are saying he was keeping it in play and using it on every combat. Cards that are 'played during combat' should be discarded at the end of combat. It's not an Item, and doesn't provide a bonus (unlike Really Impressive Title) so it can't be kept in play in front of you.

Edit: Took too long trying to find the card in my set to confirm the text before posting this, so Erik got there first...
