This is most simply combo'd with Power Word: Shield. That also gives it a better chance of survival to let your next turn's draw get reduced as well. The body is reasonable enough that getting just one card's cost reduced from this minion is perfectly fine.
It really doesn't seem like something you'd be inclined to hold until you had Northshire Cleric in hand AS WELL AS a damaged minion on board. You could, you'd just be silly to wait for it.
