New Spell Idea:Variety Spell
If you are planning on a level 6 Spell Factory, let me suggest a Variety Spell.
First, the level 6 Spell Factory will have what looks like elixer tanks instead of those blue things on the side.
The spell itself will be pink. The icon when viewed will have black and white dashes surrounding it. Any troop deployed in the ring it makes it not have a favorite building to attack.
Let's view this scenario: You are raiding a base, and you used most of your troops on destroying all the Archer Towers, Wizard Towers, Air Defenses, X-Bows, and Inferno Towers. All you have left are level 5 Balloons, your Clan Castle troops (2 barbarians, a goblin, and 7 archers) which probably won't get past the level 11 walls and level 12 cannon inside level 6 walls. So you spawn a Balloon. But it is attracted to a level 11 cannon in the corner of the map. So you place a Variety Spell, spawn the rest of your Balloons inside it, and they take out the Town Hall and Resource Storages.
This might actually work out.
