black plague bearer

First i agree with kimpan: a vampire can have only one disease counter.

Additionnally as the card "vampiric disease" is written, you put a disease counter on a vampire, but it is never said the master card stays in play. It goes to ash heap and then could be recovered (previously by exemple by such means as anthelios)...

You are right about the counter on both minions, i think i would rephrase it such as "at the end of any turn where the range was set to close"

about the example, I took at first one with no combat cards played to show a very basic situation... :
- the card is "strong" against combat ends without maneuvers and dodge without maneuvers. "Political" and "multiple action/freak drive freaks" deck will have it as auspex allows harbinger to block them and this master allows to impact them even if form of mists for example is played.
- against immortal grapple + disarm combo or against damages at close in general (rush with wolves claws and so on), this card allows kind of a side effect or small revenge but the harbinger has to rely on its fortitude to survive the fight
- against combat with maneuvers (weenie animalism with aid fro bats, guns decks,...) to long this card is useless as opposing minion is not affected as not at close
- against non wraith non zombi allies this card is strong as long as opposing minion has no maneuvers (exemple strong against a carlton, weak agzinst the ravnos ally with maneuver). Renegades werevolves and allies recovering life without action become kind of permanentmy infectly as they recover and loses life almost simultenaously
- wraith are immune and cannot carry the disease so they are by the way strong against the bearer
- zombi does not lose life due to disease but can carry the disease and cards like shambling hordes could become even more dangerous if they rush a minion with disease counter and get infected so such card would boost a shambling horde deck (even if not played by the methuselah playing the harbinger)

besides:
- habringer have almost no stealth and almost no valable combat cards, it gives a little of help to get less intercepted as blocking minion methuselah will know that without maneuver his minion will get infected and that the infection can go a long way before getting cured...

Okkkk new try:

Black plague bearer
master. Burn option.
play on a harbinger of death you control
1 pool.
At the end of any round of combat involving this harbinger, if the range was close, opposing burns a blood or a life and you may move a vampiric disease master card from your ash heap to your hand (discard afterwards)

Black Plague Bearer
Action
Harbinger of Skulls
Put this card and a Plague Counter on a minion controlled by another Methuselah. Burn this card if there are no Plague Counters or other copies of this card in play. Vampires that successfully block a vampire with this card or a Plague Counter and which do not have a Plague Counter gain a Plague Counter. Immediately burn Plague Counters from Harbingers of Skulls . Vampires with a Plague Counter burn 1 blood each time they untap, unless they have 0 blood and instead burn the Plague Counter.

Juggernaut your version is nice but there is one trouble: the counter should be burned if 1 or less blood because otherwise it would make something as following if i have a vampire with exactly a blood:
- untap my vamp loses a blood
- then he must hunt, and gains 1 blood
- next untap he loses one blood and goes hubting again... and so on...
otherrwise you have to make the same restriction as vampiric disease: no blood gain from hunting...
