With {march of the machines} down, play a {booby trap}, naming a card your opponant would not be using. Then put a {followed footsteps} on the trap.
Play a {lantern of insight}, and when their next card is revealed, name it when the trap is copied...
Even better, have a {parallel lives} down as well, to make it a one shot double whammy...

or just {prototype portal} the bomb.  lol.

True... Though the {followed footsteps} makes it so you do not have to continually pay the cost to make another one.
