For anyone who doesn’t know, Razogoth’s Heir is the reward for the “Free Tartarus” Achievement.
Berserker and Rally Free Zone
1. Mission 102: Dracorex, 5x Pummeller, 3x Blood Pool, Razogoth’s Heir = 98.3% winrate (need to play Razogoth’s Heir early!)
2. Mission 102: Dracorex, 2x Pummeller, 4x Blood Pool, 3x Banshee, Razogoth’s Heir = 91% winrate (more likely to get achievement)
3. Mission 108: Dracorex, Razogoth’s Heir, Hierophant, 4x Gatling Tower = 28% winrate (98% chance of achievement if you win)
Berserker only
1. Mission 108
Dracorex, Razogoth’s Heir, 5x Warehouse = 53% Winrate
Can be run with 3-4 warehouses and/or replace one with an asylum.
I used suggested deck nr. 2 got it on first try for Berserker Achievement. Best would be to get Razogoth out first, then have Blood Pools to heal, and Banshee take over healing later.
