I was playing a game of magic with my brother and I used the card vengeful rebirth. He told me I had to remove all copies I had of the card from my hand and library from the game. Is this true? Or do I just exile the copy I played. I have no idea please help
You'll only exile the one you cast. When a card refers to itself by name like Vengeful Rebirth does, it just means "this object," not "everything named this."
Vengeful Rebirth
