People already claiming control is dead and Glide is just too powerful for control to handle it also it ruins card advantage.. except.. it doesn't.
I will explain first of all Glide is worse than Divine Favor it costs 1 more and you need to empty your hand entirely or else you won't draw everything also when outcast vs aggro mirror it's giving your opponent fuel as well and you need at least 3 cards to NOT outcast it (it being the middle one) so you draw 2 card for 4 mana(for reference Arcane Intellect.. or Spectral Sight) it's below average there.
Divine Favor at least drew you 1-2 cards vs aggro.
About card advantage, the player playing outcasted Glide is always at a card DISADVANTAGE they draw 4 cards, the opponents draws 4 cards and then the opponent draws one card in their next turn, which means the oppponent have 5 cards and the DH have 4 cards.. also it can't have more than 5 mana to play them cause he had to at least play the last drawn card of the last turn (and there are no 0 mana cards in DH anymore), the card will be played at minimum turn 7 or so.. and by then the average control card is just better/more effective than an aggro card.
Another point- decks playing Glide will be highly telegraphed they are HYPER aggro, so you control whinners can play cards instead of hoarding them in your hand until your AOE is perfect against their board.. also it's what you should do anyway.. there's also an important factor.. your current hand isn't always desirable.. a free Plot Twist for you might be something you want to do anyway.. specially if you are quest warlock, they just healed you up with Aranasi Broodmothers.
So control is dead cause of a situational draw card? nope.. is the community overreacting? yes.
