I think most of the cards I wanted nerfed are leaving standard mode. This is a really good opportunity for Blizzard to overhaul the basic and classic sets, unfortunately it looks like they will be keeping the changes to a minimum. They're also opting to kill Murloc decks by removing reward set from standard rather than admit they made a mistake with Anyfin can happen.
If we look at the basic and classic sets, it's easy to see some big gaping holes in what some classes can do. Eg: Priest and Paladin have no early drops. I would move any two from shadow boxer, shrink Meister or dark cultist to classic set. Minibot as well except make it 2/1. Otherwise Blizzard will need to keep printing replacements for these cards every new set.
If I could change just one card in the game, it would be Knife Juggler. I think it should be either be 2/2 or 3/1.
There are a lot of other changes I would make, mostly just small changes
Leper Gnome: deathrattle 1 dmg.
Owl: 3 mana 2/2
Novice engineer: 1/2
Spellbreaker: 5 mana 4/5
Illidan: 6/6
Black Knight: 5/5
Priestess of Elune: heal 1 more
Ravenholdt: 6/6
Savage roar: minions only
Ancient of lore: 8 mana
Druid will need buffs in other cards to offset this... Eg:
Savagery: give it cleave
Bite: 2 more armor
Recycle: 5 mana
Highmane: 6 mana 5/5
Buzzard: +1 hp
Divine favor: this cards really needs to be removed from the game.
Keeper of uldaman: rare
Guardian of kings: 6/6
Tirion: ashbringer: 5/2
Ancestral healing: also gives +1/+1
Totemic might: +3 hp
Farsight: discounts by 4
Windspeaker: 4/4
Earth elemental: 1 more mana. 6/8. 1 less overload.
Honestly I would remove the randomness in shaman cards and rebalance the whole class including overload.
Power overwhelming: +4/+2
Succubus: choose which card to discard
Drain Life: 3 dmg
Pit Lord: 1 less dmg to hero
Summoning Portal: +1hp
Battle rage: only procs on minions
Master of disguise: 3 mana 3/4 1 turn stealth
Kidnapper: 4/4
Wow long post. I'd probably come up with more stuff but am on mobile and using tapatalk right now
