Hello I am here to show you how to beat this easily with Fatigue Warrior!

First of all Baron Geddon is an MVP card because there seems to be a bug where Giantfin won't play any cards if his board is empty and Baron Geddon is on the field. It's only happened to me the three times I played this boss so it could be coincidence but go ahead and abuse it.

You want to mulligan for Whirlwind, Hungry Crab, Cleave, Armorsmith, Unstable Ghoul, and Wild Pyromancer. Whenever he has Murloc Tidecaller and one other minion on the field, Cleave it because Cleave is less good later in the game. Always use Whirlwind or Wild Pyromancer + spell before Revenge because Revenge is good against Coldlight Seer buffing his board when you're at 12 or less health. Always have Death's Bite deathrattle at a moment's notice and use Unstable Ghoul and Abomination proactively because they can easily be killed by double Murloc Warleader allowing his board to survive. Whenever you see Warleader, kill it with Fiery War Axe, Bash, Hungry Crab whatever. Save Hungry Crab against Murloc Warleader, Murk-Eye, or a really big Tidecaller. If you're low on health and worried about dying to Bluegill Warrior or Murk-Eye, Armorsmith is a savior along with a taunt or Whirlwind effect. Otherwise this fight should be relatively easy. Good luck and please post questions below!
