I’m liking wintertide a lot for Kara. Never mind the vespyr part, with kinetic surge it lets her spit out three 3/3’s for five mana. Dies to plasma storm, but that’s still an even trade if you don’t lose anything else, and Kara’s stuff is more likely to be out of storm range anyway. Eighteen stat points on three bodies for five seems pretty solid.
Also, it would be nice if they gave Ilena’s bloodbound spell a modest buff, like the reverse of what they did for Ziran’s afterglow, and let you stun friendly minions. Then you could duplicate your own favorites.
