High Abbess Alura can still do some very powerful things, as seen in this deck put together by Hearthstone streamer Brian Kibler.

The hopeful outcome is to complete the Quest with this spell-light deck, then play Alura and use a cheap spell generated by either Wandmaker or one of the bevy of Discover minions to immediately play Purified Shard and (checks notes) win the game. In a pinch, Alura can be used defensively to play an Elekk Mount against aggro decks. The Nameless One is here, too.
