Sure, the game is very random, but is there at least a general list of what to do, and what not to do?
This is mine so far:
Kills are better than treasures. Focus on getting a kill, and then steal one more treasure for the win. Getting two treasures only works if the other players aren't paying attention.
Try not to get hurt first. Easier said than done, but once you get hurt, you become a target for an easy point.
Try to have 1 or 2 counter/dispel cards available. This way, you can control how nasty your opponents can be. Save them for game changing moments. If you have a lot of stones, try to keep a counter ready to negate fire attacks.
Items are powerful. If your opponent has a couple on the table, try to avoid him or her until you've got some power yourself.
Keep maintained spells and items limited to 3 or 4 at a time. Anything more severely limits your options.
