Playing 10 spell multiple times

Can someone explain how the Shamen is able to play a 10 cost spell over and over and over again? I saw no replicating of the spell or any other way that they could have duplicated it. Just wondering as it made for a really crap game.

Do you mean “From De Other Side”? There is an interaction with the card “Fate Splitter” which gives the card which killed this minion into your hand. Since the minion was killed by this spell another copy of that spell is given into the hand of the shaman.

Thank you!! It all happened so fast I couldn’t tell what the he!! Was going on hahah. Well now I know / clever. They also had the clam that made me draw cards. S It was a good strategy but would be boring a second time.
