Oh yeah, I literally only scrolled down to the first card that was shown in the card art not thinking about that there may be more. I will add those to the thread.
Looking at the last time a 7 mana 5/3 weapon was printed in standard, it was Libram of Hope, but I cant remember how much play it actually saw. And that deck had a lot of healing.
You definitly would need at least 2 blood to get the healing effects to use this. Currently I would probably go Unholy as the third just because you want a ton of corpses for the blood rune stuff, and the 1 rune frost cards just dont seem like they work well with the blood stuff.
