This OTK has medium difficulty and is quite satisfying when pulled off. All we need is to play Windfury & Rockbiter Weapon on Leeroy Jenkins while having Whirlwind Tempest is on the field to get a 9 attack Leeroy that hits for 36 damage in total. To get all those for 10 mana or less we need to play Emperor Thaurissan on of the 4 combo pieces (+ Earth Shock if needed) beforehand. To Summon the Whirlwind Tempest we use Ancestor's Call (can also be used for Leeroy)

We can draw the whole deck with the help of Spirit of the Frog, Mana Tide Totem, Far Sight, and Ancestral Spirit and got Devolve, Hex, Healing Rain, Lightning Storm, and Maelstrom Portal as well as Volcano to not die while doing so

If there is any taunt minion on the field we can play either Devolve and pray to RNGsus or we use Earth Shock to go through. Good Luck on it, the first time it worked for me was against and Odd Paladin at Rank 5 :)
