This requires the demon expansion.
Lay out the standard 4 basic cards
Draw 1 random creature with cost 3 or less.
Draw 1 random spell with cost 3 or less.
Divide up the starting dice. Each player gets:
6 Basic Quiddity
1 Corrupted Quiddity
Each payer gets 1 of the pre-drawn creatures.
Each payer gets 1 of the pre-drawn spell dice.
The remaining 3 Assistants and 2 Basic Quiddity and 5 corrupted quiddity are placed on their cards.
The rest of the setup is the same, 7 creatures and 3 spells.
Play to 12 points
Limit attacks so that a player only attacks their immediate neighbors.
Immediate neighbor attacks subtract 1 from total attack value and the attacks against the other 2 players are at -2.
We tried this variant a couple of times and it seems to work. The games are longer but in my group we chat heavily so down time and length aren't really a big problem. We didn't try the limited attacks options yet.
Also, with the new xmas cards, there's no reason you can't start with one of those creatures for a themed game.
