Nice find, Russ.
Soundman, we need to know
when Melchizedek was returned to territory. If he was returned to territory
during the battle, and his ability was not negated, then the protection continues until the end of the battle phase.
If Mel was returned to territory at the
end of battle because he survived the battle, then his SA ends after Battle Resolution.
Well, actually, either way his ability would end after Battle Resolution.
