Hmm. So, what you're doing is making dominoes, but you want them to fall. But, when you fakekill them, they fall through. Is this correct?
If so, do this.
Button: onActivate > namedbrick > domino1 > firerelay
Domino1: onRelay > self > fakekillbrick > [] [5] [] [20]
onRelay > namedbrick > domino2 > firerelay [] [5] [] [20]
Repeat.
Add delays as wished so the dominos realistically "fall".
