It backfires once the decoys start being killed, because the news that 'Dracula's dead' travels faster than the news that there are decoys in play, and his troops are demoralized by their leader's apparent death (and then also bewildered by the arrival of multiple conflicting accounts of his death).

Body Double: Dracula deploys a number of decoy body doubles during the climactic battle.

Big Fancy Castle: von Richthofen's flying circus holes up in a distinctly creepy old French castle called Chateau de Malinbois.

Been There, Shaped History: Edgar Poe mentions fighting in the Civil War on the Confederate side, more because he got swept up in the whole 'romanticized rebellion' thing than anything else.

Bat Out of Hell: Spliced with a WWI biplane, this is what von Richthofen's squadron are transformed into.

Except not only are they vampires (making them excellent night pilots) to match up to the Allies' slightly better squad of aces (which includes Expies of The Shadow, Biggles, and Captain Midnight, along with real life British ace Albert Ball) the squad is modified by science and elder vampire blood into giant bat fliers wearing machine-gun rigs.

Badass Crew: The Red Baron leads a squad of German fliers who are all vampires and aces, much like the real life Jagdgeschwader 1 the Baron led.

Dracula has a Hungarian body double/decoy named Bela.

Someone speculates that if it weren't for all these vampires, maybe World War I wouldn't have happened.

In real life he was known to be pretty jocular and friendly (the change might be a side effect of his vampirization).

Adaptational Jerkass: The Red Baron is portrayed as stiff, humorless, and almost pitiably uncomfortable in social situations.Ace Pilot: Biggles, Captain Midnight and The Shadow go up against the Red Baron, Hans von Hammer and Airboy's ally the Heap.
