Is Shipment from Kaguya a viable choice to run in a jinteki tag and bag deck and if so would it be better to run 2 or 3 copies

If you're running an actual tag-n-bag deck (killing the runner by scorched earth) that is a very hard deck to run in Jinteki and all of your influence will be taken up by just the cards needed for the kill so no I don't think SfK fits into that deck. If you're talking about running a Jinteki shell deck that tries to kill a runner by net damage then yeah you might want to include SfK into that deck since when combinde with Trick of Light it also helps with FAing agendas.

cheers for the advice ill look in to a jinteki shell deck then
