Here are my thoughts about the balance changes:
Archer Queen: Make her ability cooldown to 16 seconds, she isn’t used in much decks other than the royal hogs eq deck.
Cannon Cart: The nerf might be a bit too much, maybe reduce it to like 5% or 4%.
Fisherman: Fisherman is a balanced card, it does not need a nerf.
Goblinstein: Good nerf to the doctor, but maybe nerf the monster hp plus the ability to 3 or 3.5 seconds.
Ram Rider: The damage needs to be nerfed as well.
Evo Bomber: The damage should be buffed to compensate for the nerf.
Evo Goblin Barrel: Terrible nerf, it removes the whole purpose of the evolution.
Evo Ice Spirit: This is a terrible rework. Evo ice spirit isn’t a good evo to begin with, it’s only viable on defense, so the rework would basically be a huge nerf to the card.
Evo Pekka: All three of these heals should be nerfed as well.
Royal Recruits: Good buff.
Evo Royal Recruits: Good rework.
Evo Skeletons: Terrible nerf, this would kill the card as there will not be enough skeletons to multiply when placed on two troops (archers, ebarbs, etc).
Baby Dragon: Good buff.
Witch: Good buff.
Dark Prince: The damage should be buffed a bit as well.
Electro Giant: Sure ig.
Goblin Demolisher: Lifetime should be like 10 seconds so it will actually have a better probability at reaching the tower when used on defense.
Goblin Machine: I think this card needs a bigger buff, its pretty trash ngl.
Mighty Miner: Good buff.
Mini Pekka: Good buff.
Evo Cannon: I’m not sure about this one, I haven’t really seen people use it, so ig it’s good.
Evo Wall Breakers: Good buff, since this evo is basically useless if the opponent has a building.
Dagger Duchess: Good buff.
Lumberjack: The damage should not be buffed, since it does a lot of DPS anyways.
Let me know what yall think of my thoughts!
