Honestly I don't care about a card's score since, to be frank, a card's rating isn't helpful for building decks without taking into the deck synergy. For instance, Swashburglar is much more effective when used with Etheral Peddeller or with other pirates but alone you'd have to score it on being played solely as a turn 1 play.
I like to use Hobart in some decks to make my weapons hit a little harder. Plus, if he gets stolen by a Priest somehow he doesn't screw you as hard as say- Undead huckster can (by giving them a card)
But like I said- I don't really care about a spreadsheet or card ratings individually. I think a much more valuable tool is something like HearthArena which takes synergy into account to help people build Arena decks
Not trying to offend anyone though I can understand the allure of sitting around a desk and theorycrafting somewhat lol.
But I'm more of a Warrior. I take the tools I am given and go to war.
