Reinisch's sometime partner Ahimsah has also started a deck-grinding pacifist, now that battleground XP makes the old method trivial. She's now Acaaju, and with two players/accounts, it really helps in cross-faction trading. The more populous Horde side has a lot more cards and ink in their auction house.
She might be able to avoid the pitfalls that Mainchenn encounters, like the Stalvan quest, that can add kill credits to her statistics. I think the spiders that appear (and are aggroed) during the Deepmoss Spider Eggs quest might be a problem if anyone else is nearby and kills an aggroed baby spider, as another possible example.
