Let's take a look at what our hits might be in standard:
* Druid - Biology Project, Claw, Cyrstal Power, Floop's Glorious Goop, Savagery, Worthy Expedition, Secure the Deck
* Hunter - Arcane Shot, Bestial Wrath, Rapid Fire, Secret Plan, The Beast Within, Tracking, Toxic Reinforcements, Clear the Way
* Mage - Arcane Missiles, Magic Trick, Mirror Image, Ray of Frost, Shooting Star, Tome of Intellect, Arcane Breath, Learn Draconic
* Paladin - any secret, Blessing of Might, Blessing of Wisdom, Crystology, Desperate Measures, Hand of Protection, Humility, Sand Breath
* Priest - Cloning Device, Embalming Ritual, Inner Fire, Mind Vision, Power World: Shield, Radiance
* Rogue - Daring Escape, Deadly Poison, Pilfer, Plague of Madness, Sinister Strike, Togwaggle's Scheme, Dragon's Hoard, Praise Galakrond
* Shaman - Blazing Invocation, Earth Shock, Evolve, Forked Lightning, Frost Shock, Lightning Bolt, Totemic Smash, Voltaic Burst
* Warlock - Call of the Void, Corruption, Dark Possession, Grim Rally, Mortal Coil, Plague of Flames, Shriek, Sinister Deal, Soul Infusion, Soulfire, Spirit Bomb, The Soularium
* Warrior - Charge, Devastate, Improve Morale, Into the Fray, Omega Assembly, Shield Slam, Upgrade, Whirlwind
So make of all that what you will. At a cursory glance, most of the priest cards are ok if you're playing a midrange or control sort of game, and the shaman spells are likely to find some use. Most of the warrior spells are actually pretty good - Charge is clearly the worst one, and it isn't even *that* bad as you're giving a minion pseudo-rush for only 1 mana. Overall, it's a 3/5 for 5 that is likely to give you a couple of weak cards - so while it does generate value and card advantage, it's weak card advantage. I think it'll be a decent arena card, but won't be seen in constructed unless some sort of control warrior deck with some dragon focus is a thing.

I remembered being sad when the Heroes of the Storm curse website shut down. I never imagined that Hearthpwn would be next. I'm quite sad.

I have Khadgar already but I'm jealous of the HOTS rewards. 3 lootboxes and Medivh is a pretty good HOTS promo.

I have about four of those legendaries and 100 dust. Not to mention all the new KOTFT epics and rares. RIP

Personally I'd rather play Heroes of the Storm than play Hearthstone when I have the time. I don't need a HS hero or Overwatch skin to motivate me.

Very valid point. Card advantage is everything. Unless the cards are trash and stay in your hand. Than that can be pretty annoying.
