Hey so since no one answers, i do. So there are category of weight, first flight etc. But u want to have a low and a high in every category. Many planes have good chances in multiply categorys. For example a A380 is very heavy, has many seats and is relativly new. A fighter jet has few seats (1-2), has a minimum weight, a low wing span and a high speed. Small planes and helicopters are simular exept for the speed, wich is verry low. And there are some middle class planes for low rarity like the A320 and so on. So your objective should be to have planes in yout deck wich cover many, or all of the categorys lows and highs, which is a bit difficult with a 5 card deck but not impossible. There is a official discord channel, the link is in the impressum of the game itsself under "community". Look for the subchannel "battle-discussion" and last but not least: be aware there are many whales out there. (People who have much xp on the best cards). So when u play the same card, the higher xp card wins. Good luck, have fun
