Challengers!
Do you still resolve a card's effect when the opponent has no card to put on the exhaust pile?
The designer confirmed this, and the rulebook says to resolve as much of an effect as possible.

Yes. You resolve as much of the card text as possible. If there is no card to put on the exhaust pile, that part does nothing and the rest of the effect still happens.
