Stelina is ridiculous. 4 mana to remove what is usually the best card in your opponent's hand and look at two of the others? Sign me up any day.
Her effect ONLY goes off when its on the right or left most side, even then Glide is vastly superior.
Card wont ever see play in Tempo DH, you can quote me again in a week.
Sure, Stelina is worse than Glide. Want to know what other Scholomance cards are worse than Glide? Almost all of them. Outcast isn't much of a problem considering how low the curve is in Tempo DH, and the effect is great. She'll see play.
