Hi All.
I presume that the Corp player can play his ice into a server already rezzed.
If so, do the sub-routine(s) become active immediately (especially if they favour the Corp player)?
E.g. The corp player plays MINELAYER into a sever rezzed. Does he benefit from the sub-routine: "You may install a piece of ice from HQ as the outermost piece of ice protecting this server, ignoring all install costs"?
