A combo of mugging, Odin and carding.

If Odin appears then well... let him slaughter it. If not... then while you're mugging the Marlboro, might as well weaken it and card it. It takes, what?, 4 Marlboro cards to refine to a Marlboro tentacle? If you're going to mug 4 Marlboros (extra tentacles could be refined into spells and whatnot), might as well get an extra tentacle out of the deal....
