Wizard Tower Spells

I was thinking about it and I thought there should be wizard tower spells.
You will be able to equip your spells to your wizard towers.
Only 1 spell can be used per attack.
The amount of spells you can equip depends on your wizard tower's level.
Lightning Spell: You can equip your lightning spell to your wizard tower and the wizard will be 1.5 times stronger.
Healing Spell: You can equip your healing spell to heal your wizard tower and things around it. (It is like the spell is dropped but it will activate when the wizard tower is attacked and it will last just as long.)
Rage Spell: Just like the healing spell but will do the rage spell effect.
Jump Spell: Just like the healing/rage spell but will "Jump" your defenses range. (It will increase your defense's range.)
Freeze Spell: It will freeze all of the troops on the screen when in range of the wizard tower. The time is the same as the spell's normal time.
