Skeleton Army is a strong card versus single targeting troops. It is composed of 20 Skeletons that can easily destroy troops and buildings if not countered by splash damaging troop or spells. They can dish out damage quickly that even tanks like Giants can’t survive long enough to reach your towers. They can be used defensively against tanks, and single targeting troops like Mini Pekka and Prince. They can also deal good damage against the Arena Tower alone since the solo Arena Tower can’t kill 20 Skeletons immediately.
