can you be targeted with discard a card with no cards?

[Arix]

Yes.

[Backpack]

and...?

[Arix]

And...what? Yes, you can. Was there another part to your question?

[DatAsh]

Why would anything else happen? You're a legal target, but you have no cards to discard, so you ignore that part of the card. If the spell is like Mind Rot then it resolves and nothing happens, but if the spell is like Blightning then the player will still take damage, regardless of if the player in question has cards in hand.
