I'm sure that this has been answered before but i didn't see it anywhere in the search! Sorry
When you use Kabuki Artist, and you have no momentum, what happens? Do you get to search your discard pile for any card? Or no card? I figure the do as much as you can rule comes into effect.
Kabuki Artist : E Commit: Reveal your momentum. Your opponent discards 1 momentum revealed this way. Add 1 card from your discard pile to your hand. The added card may not be the same card type as the discarded momentum.
