If I choose Eastern Ops with with this card silenced in my tableau and during he course of my ops he becomes un-silenced do I suddenly gain the written card ability "May do east & west ops in one action" during that Op action? Can I suddenly also play my way ops during that action?
No. In the Flow of Play (A2) it states that one of your actions is to:
"enable the operations (Ops) of your cards in either the east or west side of your Tableau," Once you have enabled this action, it cannot be retroactively enabled with a new ability gained as a result of this action.
