I guess, this is it. That AI world is currently not well balanced for new players or players who won't spend actual money for the game (as a beginner). So, to tell you the truth: If you are not willing to first invest real money into the game for this world I suppose you will be really lost. That AI world really requires you to first invest cards and cardpoints to be able to survive - not a good world for beginners.bad mistake of joining an AI game type world ?
Therefore, I'd suggest you to try it on a non-AI world first, were the AI
1) is not that strong
2) won't destroy your village
Good luck!
