Here is a list of my CoC ideas: Goblin Chief - Special ability is a magnet that suck in resources within a 5 tile radius. Max Level stats: 2000 HP, 200 DPS to resources and 50 to other, summons goblins when under 1400 HP, summoned units are relied on the level. Finally, the ability would be called Mega Magnet.
Wall Battlefronts - Once Town Hall 7, Air troops become a pain. But no fear! Once you are this Town Hall level, you can unlock 25 Battlefronts for walls! Battlefronts stop air troops from plying over them, and the air troops need to attack it to destroy it. It is attached to walls, and by Town Hall 10 the maximum you can have is 100.
