No, glide would not be good in a control meta. Four mana to conditionally draw four cards is actually very slow right now. With an otherwise empty hand demon hunter can pay two more mana to draw three cards and reduce their cost to zero or reduce their cost by three; they can also spend two mana and draw three while playing a 1/3 minion that must be killed. Rogue literally spends one mana to draw four cards.
If played on turn four, glide sacrifices an entire turn worth of tempo and could actually help a control player stabilize. If played on turn eight, there is a good chance the control player has already stabilized or lost. I guess glide could grant demon hunter mediocre turns 5, 6, or 7.
Glide is also a terrible card to get in a mirror matchup.
played against a reno DH in wild today and got totally wrecked by Glide. Had several discounts on my cards thanks to Emperor and would have won the game. he played Glide and from there on it was an easy game for him. In Control Matchups it's one of the best cards to have, especially as DH who doesn't give a fuck about reducing his own hand size with so many drawing cards in the class
