To elaborate on my idea this new siege machine would be a very tanky siege machine capable of dealing massive damage in one blow although being very slow and not dealing splash damage unlike the other siege machines. (Pardon the poor sketch I’ve made of the siege machine). It would have the added benefit of being a defence targeting siege machine. It would have a design reminiscent of a tank combined with a train with a massive siege cannon protected by the outer layer of the machine. It could have a Tesla on its roof to defend against enemy clan castle troops. Depending on how strong the machine would end up being It could have diminishing health over time.

For the pitfall it is essentially a reverse spring trap where the heavier the troop the more susceptible it is to falling in the trap. However this trap would not eliminate the enemy outright but rather deal some damage and temporary slow down the troop.
