Xantcha, Sleeper Agent

Xantha, Sleeper Agent

*Xantha (opponent = owner and under my control) versus Ghostly prison, I am still forced to attack when I do not pay for Ghostly prison, and then can not proceed combat.
*Xantha (opponent = owner and under my control) and Teferi's protection. She did not return and wasn't found anywhere. The game for the owner froze.
*Xantha and Mystic Barrier. If the barriers direction is chosen to attack Xantha's owner Xantha is forced to attack still and game freezes.

1. This is Xantcha, not Xantha - mentioning so that I can find this issue in future searches

2. Likely related to Xantcha caused lost priority in an EDH game #5482.
