Your final assessment of "6 total mana" matches my original intuition for what my card should cost, though.
I was using burglar rat as my basis, which is either slighly pushed or slightly underpowered. Vicious Rumors suggests slightly underpowered then, so 6 is a good approximation or if you want it to be a pushed card.
