I'm thinking for the 4th spell in the dark spell factory, or the 6th spell in the spell factory, that there should be a lure spell. This spell would lure troops to the area where the spell was placed, even if they were destroying a building. If this spell gets added to the game, I think it would be neat to try to use with a jump spell. Here are some stats:
Level 1 time: 20sec
Level 2 time: 27sec
Level 3 time: 34sec
Level 4 (Max Level) time: 45sec
