I would not be so sure. I have not played to posted in a long while but I still look at this thread from time to time. You never know when someone will come back to help out.

If you absolutely want to minimize luck. The best way to do that is to increase the number of units. The larger the armies the less luck is involved. There are a few ways to do this like making cards more worthwhile or a number of other ways.

Thank you very much.

I agree with waltero but maybe for different reasons.

If you tell your opponents your strategy or how to beat you they will do one of two things. Generally, if they are not a good player they will take you at your word. This makes them feel grateful to you and less like to attack you and get lucky ...

I can think of a number of reasons why a player would attack you like that, none of them assuming that they are bad.

If there are three players left, a strong player, you, and a weak player, the weak player may be convinced by himself or the strong player that he will lose no matter what happens ...

I was just reading further about this online, after reading this post.
According to a number of places the best stat for invading is 1.5 * number of armys + number of territory.
I don't know if this is true, but lots of place seem to agree.

Geez this will really save me lots of troops. I have been using 2x until now.
