This thread is for discussion of this week's Uncharted Realms, which goes live Wednesday morning on magicthegathering.com.
The flavor of this card is odd. A desperate stand is a defensive situation (as in this very story), but this can only be used for attacking.
I believe it is a re-imagined Battle of Thermoplae, as heavily implied by the art. One of the key points about this was that the defenders were decimated, but they inflicted heavy casualties on the attackers. So a toughness bonus would be inappropriate, but a temporary power increase would be in keeping.
The Spartans did not retreat, so vigiliance seems wrong. Myself, I think it might've been more appropriate to remove vigiliance, maybe make it a +3/0 but make it so you had to sacrifice the blocker.
As a nice strand of the writing of this story is the soldier's consideration of fame and glory as a Gift of Immortality, as the attackers in Thermoplae were called the Immortals.
Works for me, on several levels. Cool writing!
