Control Warrior with the aim of drawing as fast as possible to assemble the following combo:
King Togwaggle -> Explore Un’goro
If they swap back you destroy their deck (that now consists of one cost spells thanks to Explore Un’Goro) with Skulking Geist (which is in your hand) and win with fatigue.
If they don’t swap back you’ll also win simply through fatigue because their deck will be thinner than yours thanks to you drawing more cards before pulling off the combo.
