6 ways to transport the undead south of the wall on 'Game of Thrones'

In the most recent Game of Thrones episode, our heroes had a Very Dumb Idea: To bring someone from the army of the dead south to King's Landing so that Cersei will believe it's real.

Um...okay?? We don't know a lot about the thousands of undead soldiers marching toward Westeros, but among what we do know is that A) they are murderous, and B) do you need more?

But since the Eastwatch squad is already en route and Daenerys and Tyrion have signed on for this hair-brained plan, the least we, the citizens of this fandom can do, is offer some advice.
