Let Togwaggle's Scheme build up to at least 7 shuffles, then play Tak Nozwhisker and Mogu Cultist, then Scheme on the Cultist.

Alternatively, you can just use the deck's plethora of card draw to get the necessary 7 Cultists in hand.  Once you have them assembled, play all 7 to summon Highkeeper Ra and then play Drakkari Enchanter for a 40 damage combo to all enemies.
