Loatheb seemed tough given that he has 99 health, can deal 3 damage to you per turn (ignoring army) and especially because I read the spore text wrong (I thought if you killed it, it gives Loatheb’s minions +8 attack). Once I understood it, this made the challenge much easier. Here’s my deck:

  • Flash Heal x 2
  • Holy Smite x 2
  • Light of the Naaru
  • Power World: Glory x 2
  • Northshire Cleric x 2
  • Convert
  • Resurrect x 2
  • Shadow Word: Pain x 2
  • Thoughtsteal x 2
  • Velen’s Chosen x 2
  • Dark Cultist x 2
  • Dragonhawk Rider x 2
  • Shadow Madness
  • Holy Champion
  • Holy Nova x 2
  • Holy Fire x 2
  • Temple Enforcer
  • Confessor Paletress

I started out with a Warrior build to do AOE damage, but after 1 game where I realized what a Spore actually did, I switched to Priest. I won in my second match as the spores pumped my minions up way too much. I had a 27-6 Windfury Dragonhawk Rider and took down Loatheb from 52 HP on my last turn!
