Board Game Arena

I think I have good knowledge of the base game but when I play arena, things are quite hard. I always end with a lil bit less VP. May be bad luck, but it's probably me doing something wrong.
So I want to ask for some kind of advices or tutorials.

I think this is a good guide, even though it's aimed at base+TGS and mostly about starting worlds it contains a lot of correct ideas about how to play. https://boardgamegeek.com/thread/519101 ... 2pa/page/1

Good guide indeed
