I would go for a Mythical, Cryptic or Conquest sword if you use Fanaticism aura. A Phase Blade is awesome for a Tesladin, but not that good for a Zealot. Too low damage. With a Phase Blade you need a lot of Crushing Blow to deal some serious damage to monsters.
Static from Crescent Moon can do the job, but remember it only affects monsters with more than half of its hit points. And don't expect cast Static as often as with Schaefer's. 7% chance of casting is like 1 cast out of 3 complete zeals.
