Bug Sundial + Pommel Strike+

[Stagow]

I encountered an invalid infinite with the said cards.

Relic: Sundial
Library: 0
Hand: Pommel Strike+ (PS+), any number of other cards
Discard pile: Pommel Strike+

If you play a PS+, the Game tries to shuffle twice, while drawing the PS+ from the discard pile.

Playing 2 PS+ gives you 4 shuffles, resulting in a net gain of 1 shuffle = infinite damage and infinite energy.
