I searched the forums and there were no results. I was playing today with a machine wraith and some questions came up.
When my wraith takes control of a jack, does the jack lose upkeep spells on it?
Is the jack no longer a friendly model for the opponent in terms of targeting?
When does the other player spend focus to try to regain the jack, during the casters activation or when I activate the jack the next turn? the wording is rather unclear with the uses of It's.
