Assuming this doesn't draw a card if the next card is the exact same Cost, it feels like you would need to build your deck in a very specific way to make this more than just a worse Wrath. I'm not sure it's worth the effort.
If you have Mecha'thun, I was just able to beat the Lich King with Paladin using a Mecha'thun+Skaterbot+Subdue combo (with 2x Galvanizer to discount the mechs). The deck I used had a few wild cards in it, but the ones it had were either card draw or heals to help me stall out the game until I drew out my deck and not actually necessary to pull off the combo itself. There was a Warrior deck I borrowed from the internet that also used Mecha'thun to beat him, but I can't remember right now if it needed any wild cards.
