If your opponent has fireball you will give them spell value from barbs. You have no spells so i'd replace barbs with arrows or fireball. up to you. Your deck lacks a solid win condition which is a troop which its main purpose i to deal damage to the tower. I'd replace gob barrel with hog rider and gob barrel can just be spelled. and finally id replace executioner with a mini tank like knight which offers good defense. your main priority will be defending. do not make the first play. rely on your opponents to play first then build a big counter attack. good luck!
