Given the prevalence of lead Pursuit Tyranitar, you're going to quite often start off 6-5 and without a spinblocker. I would suggest you instead lead with your own Tyranitar to prevent Gengar getting trapped so early. I'm not exactly sure you need Crunch so you could always run Hidden Power Grass on it because Swampert can be somewhat of a nuisance because while it 'can't do much' to your team, you lack really many options to hurt it.
If you keep Gengar as your lead then definitely give it Destiny Bond over Taunt so you can at least take down lead Tyranitar with you. I don't really think lead Gengar needs Taunt that badly, while being able to take down Tyranitar is a huge help especially since it's often many team's best answer to your Zapdos.
Just little nitpicks, I'm not much of an ADVer lol.
