Do opponents see your alternate hero?

In Hearthstone you can use a few different alternate heroes for yourself, which are basically just skins and provide no benefit other than a cosmetic change. I bought the Magni Bronzebeard warrior hero since I dislike Garrosh.

I haven't been playing Hearthstone particularly long; however, I've been playing fairly regularly the past few weeks, and after buying and using this skin I realize that I've never actually seen any of my opponents using an alternate hero.

I know from reading different sites that the price of alternate heroes was a bitter subject for Hearthstone players. I think that surely I should have run into someone else using one of the currently available alternate hero skins by now, though. I haven't even seen anyone using the Lady Liadrin hero, who is completely free to obtain.

This has led me to wonder: Can opponents even see your alternate hero skin?
