***TRIALS RESPONSE***I tried this version and noticed it to be remarkably consistent for being a trio, Phase Shields are much more useful than Bone Walls if you're using them to buy some time to set things up, though this requires your opponents to not have permanent control to stop your Dimensional Shields early, not have quanta control to damage this quanta fragile deck AND not have creature control to kill your Parasites before they can infect your Dolls.
To be honest, the Darkness war version of Shields + Parasites didn't work as well as I had hoped. So I tried combining both ideas and came up with this (see below). It can deal with creature control, by playing Parasites after Bone Wall and Voodoo Dolls you can make your opponents' own cards backfire against him, as long as you have Arsenic to back up your damage. This deck is also less vulnerable to permanent control since Bone Walls aren't just blown away by a single card. Since it uses only one kind of Pendulum it's draws are more consistent, too.
Though it all depends on what kind of opponent you intend to face with this deck. I personally think this version is more suitable for pvp for being able to deal with more threats, but Dimensional Shields work well enough as long as they remain undisturbed, and your version uses these nicely.
