Infinite Flying Zombies Combo (Standard)

A fun and crazy 4-card combo piece that can give us infinite flying zombies as early as turn 5!

Basically with Desecrated Tomb and Arcane Adaptation (naming zombies) on the battlefield, we can cast Liliana, Untouched by Death and ultimate her right away to cast zombies from the graveyard. With Chamber Sentry either in graveyard or in your hand, we can cast it for X=0, and when it dies, we cast it again infinite times as Chamber Sentry is now a zombie. This will trigger Desecrated Tomb, creating a 1/1 flying Bat token who is also a zombie, therefore making infinite flying zombies!

For Arcane Adaptation, if we have multiple copies, we can cast it naming Demon so that we can also have an alternate win condition in Liliana's Contract. Arcane Adaptation naming Skeletons is another option with Death Baron on the battlefield.

Due to Liliana's Contract and Desecrated Tomb needing lots of creatures, we fill up the rest of our deck with utility creatures.
Reassembling Skeleton is the best card with Desecrated Tomb.
Graveyard Marshal and Memorial to Folly can also trigger Desecrated Tomb.
Dusk Legion Zealot and Midnight Reaper helps us draw into our key pieces.
Ravenous Chupacabra, Hostage Taker and Plaguecrafter are our deck's removal.
Even Chamber Sentry can be utilised as X=2 to kill off any small toughness creature 2 or less.

I know that this deck is hard to be made competitive as we have 2x playsets of 3-mana do nothing cards, but otherwise Infinite Flying Zombies is fun especially when we combo off!

Any suggestions / comments always welcome!
