I just played verse a Bloodfang deck. Right at the end, the opponent tried to use Shaman to place target ally from Graveyard to Hand, it didn't allow him to seek through graveyard. Then he played Wulven rally, it allowed him to seek ally to place on top of deck, but when he chose next ally it stayed in the graveyard.

Can see BT FizzyBurnsRed v 1682120 match for visual. It is right at the end of the match.
