Countdown tile tap/hover effect

It would be a nice UI improvement, and hopefully relatively easy to implement, if when you touch or select an enemies countdown tile it highlights in some way the enemy it placed.

This could be done through a number of ways, an outer glow on the hero, bringing that character to the front position. With multiple characters of the same name simply just adding the name to a tooltip would not be enough information. Perhaps you could add Character Name (position {1-3}) or something to that effect.
