And just because you can make up one scenario it means it will be bad?
How about
Moonforge Lancer 2/4, 3 mana, Whenever an enemy general or minion is healed give +1 attack to your general
And then play it against Abyssian with Kelaino on board or Shadowdancer. Then immediately in your turn get value by making a few minion trades. Then the opponent has to waste hard removal on that minion. Still bad? Or how do you think that minion would perform against Ziran?
