Ward Control

[Drunken Dragon]

Not sure what I would call this unit, but he could take control of a ward as long as he maintained focus... Imagine how cool it would be to steal your enemies lightning ward for a few turns or use their barrier ward to protect your troops.
I know a Telepath has already been suggested, which I feel would be a bit to powerful, but this is a nice alternative.

[Sen]

I don't think that's a very good idea...
It would make putting wards into your roster dangerous, and defeat the purpose of the wards, defence. You have your last few units huddled around your Lightning Ward for protection, and he takes it over, owns one peice and then the ward is useless for the next 4 turns, giving him even more time to rape your units.

[Krazor]

It's all in the strategy, keep the bugger away from your wards or break his focus.
