What advice would you give for other keepers?

My tips:
- Get yourself in the mood with a Slayer song at the start of a game (particularly World Painted Blood or Hell Awaits), which can make it easier to get into the mindset of an evil overlord.
- Plan out your dungeon in advance (frex, have an area reserved for lairs, treasure rooms etc.) before you access your portal. Management of your dungeon space is vital especially when resources are scarce.
- Make note of what you have at your disposal, and plan accordingly. Not much point to marshaling a massive army only to find that you cannot pay for it now is there?.
- Only use Armageddon if you know for certain that you are going to win, otherwise it won't be pretty.
- When using a transfer creature, remember to ask yourself this: "how much use will this creature be?"
