So to conclude, no, it is not easier to set up than a kadouha.

Edit: And the above of course, applies only if you start first.

Just the fact that you need to Power-Up fully, which takes one turn to do so, differently from Eclair Lacroix which requires no setup at all to throw it out is what Grandpa means. Your arguement is too focused on Voidgates itself rather than the actual skill, meaning that yes, Kadouha has more setup than Eclair Lacroix.
