Was just looking around at different mage cards and decks but I was wondering is there were any viable Frost Lich Jaina decks. 

I love all the DK cards, but they kinda seem outdated? Anyone have a way to build around her?

Saw her being played two months back, normal deck with elementals. Could be fun with Renathal as you have higher ceiling to heal. Also better chances to get there. But don't know if it would be viable. Most elementals used in Mage are rather slow and outdated. There are few interesting new here and there but 9 mana is rough for her.

I have special place for Garrosh, I do play him in my even deck. Nice to see other fans for DKs.

Nope, she's way too slow for the format unfortunately. I guess you could build an anti-aggro deck with her but she wouldn't be the reason you win the game against aggro most of the time, because if you're turn 9 against aggro, it's already over for them.

For perspective, in Wild mages open the waygate on turn 5-6 and follow up with ways to cast it multiple times, resulting in infinite turns for the mage. And aggro wins by turn 3-4 against such combo decks, because they have to.

Basically at 9-10 mana you need to play something that immediately wins this turn or the following turn, like DK Gul'dan, and even then, you won't get to 9 mana very often anyway.

High cost cards with slow, incremental value over multiple turns like DK Jaina are simply and utterly useless.

Maybe if the water elemental had taunt it would actually be worth playing against aggro.

Maybe Hero Power mage but I don't really know

I'm a huge fan os this card, but sadly Magister is a better hero card, but I always try to make some reno variants, so I have this right now:

Isn't perfect, but its performing good against aggro and can win against combo/control aswell, but you can change 10 or more cards or even add 10 more cards with renathal and still will be viable, that's why I love control/reno decks.
