What is the name of yu gi oh card that makes you take 500 points damage and inflicts 1000 to your opponent?

There isn't a Yu-Gi-Oh! card that does exactly that. There are cards that inflict damage to both players, but they don't have that exact damage ratio.

Here are some examples of cards that might be close to what you're looking for:

* "Painful Choice": This card forces your opponent to choose between taking 1000 damage or you taking 1000 damage.

* "Mirror Force": This card destroys all face-up Attack Position monsters your opponent controls, but also destroys all face-up Attack Position monsters you control. This can indirectly lead to damage in some scenarios.

* "Chaos Emperor Dragon - Envoy of the End": This monster's effect can inflict damage to both players depending on the number of monsters on the field, but the damage is not specifically 500 and 1000.

If you're looking for a specific card, you may need to provide more details or a description of the card's artwork.
