Oops. Yeah, now that you mention it, it does sound like it could be interpreted that way. How about this? "Redirects Reverse Time towards self." or "While in play, only this creature can be targeted with Reverse Time."
Tucking Fypo @ Well the idea is in present time this robot is ancient, but if rewound to when it was in its "prime" it's no longer ancient. Maybe something like "Rusted" or "Ruined" might be better?
And what do you mean by your last comment? Does it seem too "niche"? Would you prefer that the ability works with other CC as well?
