2 questions about Lysandre trump card

[pokemonrocks777]

Hi I had a pondering question at one of the events I attended and I was starting to pondering

My opponent plays Lysandre trump card I show him my discard while he just supposed to show as well to show there is no other trump cards in the discard?

another question

Can Lysandre's Trump Card be played if there is only a Lysandre's trump card in either players discard pile?


Wording on


Each player shuffles all cards in his or her discard pile into his or her deck (except for Lysandre's Trump Card).

This is Ponderous.

Yes, if either player is unsure or even just wants to see the discard piles, they can be looked at. Of course, this can not take up a lot of time.

If there are no cards in either discard pile other than Trump cards, then it can't be played.
