Machinedramon built with the intent to trash security for existing, using collision and analogman redirct to activate trashing security effects.
the alternate trailmon is probably a safer option for pulling tamers, but playing them for free is the gas this deck needs.
bees are a good way to stack 4 security trashes with 1 ex1 machinedramon play, but they lack any function otherwise, its better to add a second rapid & tyranno when you digi into chaosdramon and leave the bees out of the deck all together.
D-Reaper egg will protect against delete highest dp effects.
