This is the deck that I used to fight world bosses: Arboria, Dagdan and Yakkar.
Main point is to boost and amplify wind wisp with haste creatures. I added Shaytan Monstrosity for backup in case wind wisp is defeated. It will inherit the attack power to Shaytan Monstrosity.
To amplify the attack, you need to directly attack the god. So I put creatures that has haste attribute such as Wind Soldier, Demonic Salmon and Oradrim Monk. If you don't have the cards, you can use other alternatives like Flash Salmon or Khalim Follower.
I also add some movement support such as Windborne Champion and Flash Wind. They will be useful to create a space for more attacks. After all, you will need a space for Wind Wisp to attack. If that fail, at least you have Shaytan Monstrosity to absorb the attack point from Wind Wisp.
