I'm not playing ranked yet, but in casual i see alot of people running it. Mostly to counter weather decks or to thin their decks. As you said, it's never a dead card.
If you're running a special heavy deck (like the special scoia'tael archtype) then its a nice way of increasing the chance of pulling out bronze unit cards (Dol Blathanna protector) when you need it.
If you do not run clear skies and meet a weather deck, you might be in big trouble. Not to mention it's needed to counter the gold weather like drought and rag nar roogh
