While Harad decks are relatively recent, I figured I would check out what is out there, and then revisit it after the current cycle is over to see what has changed. Unfortunately, they are few enough that the sample was awfully small, and I ended up choosing between Harad w. Erestor, Harad w. Outlands, and Harad w. Vilya. I did the last, since Elrond was the single most popular hero paired with Kahliel. You can find the analysis here:
