We ruled that it did work, and that the effective capacity depended on
the number of Orun on the minion at the time BP triggers.. but weren't
totally sure.
Orun: Master: trifle.
Put this card on a Laibon. For non-Orun cards played by Methuselahs
other than this Laibon's controller, this Laibon is considered to have
2 additional capacity. A Laibon gets an additional vote for every
three Orun he or she has. If this Laibon successfully bleeds for more
than 2 or successfully performs a (D) action against a non-mortal
minion, he or she burns one Orun. Burn this card if this Laibon has
more Orun and Aye than his or her capacity.
Baltimore Purge: Action
Requires a ready vampire.
If this vampire is Ravnos, this action is at +1 stealth. Put this card
on the acting vampire. During your untap phase, burn this card, and
each other Methuselah chooses a ready vampire he or she controls who
is not older than this vampire. If you control a ready Lasombra, you
choose the vampires instead. This vampire and the chosen vampires go
to torpor.
If BP is playe by another Methuselah, yes.

Triggers.

Correct.
