The R.O.Y.A.L.R.O.O.K. System:
1) Read the Milestone and Awards: they matters a lot on how to evaluate a card.
2) Only Buy good card, buy card bad, passing doing nothing not so bad. Till you get gud, keep less than 5 cards, buy only 1 card each gen.
3) Yes to earth cat, AI Central and Anti gravity technology: em good.
4) AI is gooooooood
5) Local Heat Trapping win you games, you probably want to keep it.
6) Restricted Area is considered by some even better than AI: it's gooood.
7) Oceans are actually really cheap to SP because of the rebates: especially when it help you to convert a greenery, save cash for moments like that.
8) Ocean walking: "walk" your greenery along the ocean, especially as ecoline, points are bad, ocean rebate gooooood.
9) Kill your opponent's outs: does this card gave your opponent an easy milestone? Then it costs you a 10 points swing by passing it.
But most importantly: Just Play More Games, doesn't even try to win, just play more, it's the only way, you have to play till the point that you don't care about winning or losing.
After playing a bunch of games, then go to a good player's profile and study their games especially between two good players. You are so spoiled here on BGA where all the games are open for all to study. Back my day when I tried to get better? I download logs upon logs of player's game data and study them over, and yeah all the positions are just numbers I have to visualize them or have a map next to the log. You won't get better by just being info fed by reading or watching, things can just go over your head. You have to study them on your own.
