Complete Quest - Survive the onslaught.
- Ditch every card in the Mecha'thun Combo.
- Keep Prince Keleseth (no brainer)
- Keep lost cost taunts
- Pray to RnJesus that Keleseth is drawn to secure win.
6 Card Combo to finish make sure you have.
- 2x Inner Rage
To do combo play in order
- Boomship to summon Mecha'thun and Malygos
- Use inner rage on both Mecha'thun and Malygos
- Then finally use Whirlwind
The only thing that can stuff this is "Skulking Heist"
But hopefully the Quest and Taunts will suffice the Mecha'thun is only a backup before fatigue sets in. Good luck and have fun.
