Blizzard, it's not too late to fix Poisoned Blade...

• 1/1
• "Your hero power gives this weapon +1 Durability instead of replacing it."

Fixed, playable, balanced, fun. Deadly poison and Tinker's Oil now have a card to combo with other than blade flurry.

Overall, it would be a much better way to get continuous value from the card, and allow you to get repeat value from deadly poison and oil.
