[Serenity]

Desirable and undesirable are in the eye of the beholder. If I really want Marcu to move closer to the action (perhaps so I can use a future order marker to reach a particular space) then I might actually wish for my opponent to take over Marcu and hopefully move him to a place that will be advantageous for me in the future. Perhaps the Myrddin language should state that Marcu is affected rather than benefits however.
