this much more recent card text makes the ready/uncontrolled situation clearer. past card texts state RESTORE, 2008 onward state FILL.

restore indicates the vampire already had blood on it.
fill has no such premise.

There is no text on this card specifying non-standard targets (unlike for instance on Enchant Kindred, Govern the Unaligned or Tend the Flock) therefore, it follows the rules. Since it follows the rules, you cannot choose an uncontrolled vampire for Giant's Blood.

a vampire is still a vampire, be it controlled or not.

Blood Doll

Master

Put this card on a vampire you control. During his or her master phase, this vampire's controller may move 1 blood from this vampire to his or her pool or from his or her pool to this vampire.


Why would such cards state controlled if such text is redundant as per 1.6.1.4?

Whether it's a vampire or not, the rules say that you can't use Giant's Blood on it since it's uncontrolled.

Put this card on a vampire you control. During his or her master phase, this vampire's controller may move 1 blood from this vampire to his or her pool or from his or her pool to this vampire.

So you can't play it on an opponent's vampire.

To stop you putting the card on someone else's vampire. You can play Giant's Blood on any ready vampire (including ones you do not control). So rather than saying "Fill a ready vampire to capacity" the text relies on the Targeting rule to allow you to only target cards in play.

1.6.1.4 Restricts you to targeting cards which are controlled or 'in play' unless there is specific card text. Uncontrolled vampires are not 'in play' and therefore cannot be targeted by a huge number of other cards.

You cannot put discipline cards on uncontrolled vampires due to 1.6.1.4
You cannot play Anachronism on an uncontrolled vampire due to 1.6.1.4
You cannot play Society of Leopold on an uncontrolled vampire due to 1.6.1.4

So you can't choose an uncontrolled vampire for Giant's Blood.
