New spell

More spells would be awesome! Currently their are only 4 spells plus santa's SUPRISE whichever comes out only at Christmas. Extra spells would definitely make the game more interesting more spell would give people who have done everything more stuff to do there should be spell that do stuff like slow down the attack speed of the defenses around it or a spell that makes you troops undetectable for about 30 seconds or stalls the defenses temporarily, or a spell that will teleport your troops to where it was dropped but the troops must be in a 4 tile radius or something and the higher the lvl the bigger the radius. Please respond.
