Praise Galakrond! Or don't, since its likely on the chopping block along with other overperforming Shaman cards in a balance patch scheduled for some time next week, as confirmed by the PlayHearthstone twitter.
Assuming it arrives on schedule, this will be the fastest balance change in Hearthstone history.
We’re currently working on a balance update that will arrive within the next week containing adjustments for #DescentofDragons, including some changes aimed at Shaman.
Any cards that are affected will be given full arcane dust refunds. Stay tuned for more details next week.
