Standard UW Spirits Deck updated for Amonkhet. Would love recommendations for tweaks if you have any.

I had retired it after the banning of Smuggler's Copter and Reflector Mage, but had a hankering it bring it back for Game Day.

Mausoleum Wanderer fits the theme, but it doesn't seem to play as effectively as I would expect it to.

Essence Flux is one of my favorite cards in the deck both from a protection from removal standpoint, but also to buff spirits in a pinch.
