In order to gain enough cards for Variable Cord to be good, most players use the draw trio. Other worlds do not have this kind of support for Variable Cord, he's very very unhelpful in other worlds. But as for Liberate Cannon, its still a gamble whether you can get the draw trio to work fast and consistently.

Oh, as for Liberate Cannon, any deck with Jackknife SD and monsters that gain soul by itself should do it. I can think of a way to get 4 souls really fast.
