You could also take
inspiration from this combo that was Infinite Flying Zombies Combo of Mister.Ri , it look like it could have a nice synergy
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!
