Nobody is using Ice Barrier. I watched and read quite a few guides, not a single one works with that card.
Tbh no Tempo Mage pro-deck has the Healbots either. AND almost no taunts (one Mirror Entity at best). I don't get it. I watched a few
videos and it seems those guys just accept they're gonna lose against hunter (and they do). They don't build their decks with aggro in mind as if it just wasn't worthwile, since Face Hunters are too rare in the highest ranks (maybe because they're crushed by Handlocks and Warriors?).
Maybe that's why Hunters are so reviled - because you just have to accept you're gonna lose to them unless you get lucky with a perfect hand.
