Can Reprieve prevent a character summoned with Kitsu Spiritcaller from going back under the Dynasty deck?

Yes

But, unless you manage to get fate on them some other way they are still discarded at end of turn.

Thanks!

Although they are now back in the discard ready to be summoned up again next turn so its not that bad. Plus its not like Lion doesn't have a few methods for getting additional fate on characters.
