Honestly the balance in this game is all fucked up.
Lyonar is super super duper mega strong. He can just charge you and summon huge shield guys with 0 attack and 5 defense on his second turn that force you to attack them, make you unable to run but he can easily cast spells that make their attack as strong as their defense, also they have zeal which means when they are standing next to their general they get +3 attack and in just a few turns absolutely pulverize your health. So by turn 3 they're 8 attack 5 defense, you can't target lyonar himself or flee at all because your provoked and early game there's almost nothing that can be done to kill them because of their high fucking defense. Unless you're playing Abyssian and have removal spells. Even then you'd be wasting your instant creature removal spells on a 3 mana creature.
It's pretty fucking annoying, if you see you're playing a lyonar player just concede or acknowledge that you're going to lose.
