I have a rough idea for a troop that has incredible health but does not do damage. Also all defensive towers but hidden tesla attack it if it is in their range and ignore other troops. It's movement speed is 24, just enough to stay out ahead of the other troops. It would be called the Nemean Lion a mythical creation that has a coat that nothing can pierce but it can still die. It is a dark troop that would cost 500 dark elixer at lvl 1. It takes up 25 spaces and takes 30 min to train.
Good idea or not just let me know.
If people like this idea i will go into more depth
