The gargoyle created by "Create Gargoyle" is unique or not?

Name: Create Gargoyle
[BL:U2, LoB:R, HttB:PGar]
Cardtype: Action
Clan: Tremere/Tremere antitribu
Cost: 2 pool
+1 stealth action. Requires a non-sterile vampire.
Put this card into play; it represents a 2-capacity slave Gargoyle of the same sect enslaved to the acting vampire's clan with basic Visceratika [vis] and flight [FLIGHT]. You may search your hand, library and/or ash heap for a master: Discipline to place on this Gargoyle. Move up to 3 blood from the acting vampire to this Gargoyle. This Gargoyle cannot act this turn.
Artist: Durwin Talon

Most cards that create vampires set if the vampire created is unique or not.
A few not.

Hatchling and Raw Recruit doesn't set is the vampire created is unique or not. But According to VDB by LJS sets that is not unique
Although I don't see any reference to Hatchling in the LJS link so I don't understand why that applies to Hatchling

Is there any generic rule to set if a vampire created is unique or not when the card doesn't set it? Maybe if the card doesn't set a name for the card, in that case the vampire is not unique?

For example Create Gargoyle doesn't set if the vampire is unique/not unique

Thanks.

Hi,

The crated gargoyle is not unique as it is not named.

Minion cards are not unique by default, including cards that are put into play. If the created vampire is unique, it will need to be mentioned explicitly on the card to override the default, cf. Nosferatu Bestial.
