This game is about 70% Luck, 30% Skill. So seriously, stop crying. If you can't predict what you're opponent will do, then this game has nothing wrong. Just like every other card game, you must predict and actually THINK about what the player will do. You don't just randomly do something and hope for a good outcome. So really, you are just complaining about yourself. Yes, but luck does come in when you actually DO predict what you're opponent will do. So for the people who don't know how to think, stop crying.
Sorry for spam but also, every characters strongest attack (AKA costs most energy) should always hit the switching opponet. Its kinda gay when you whats like 60 energy, while the opposing character can just switch out untouched.
