1:choose creature type other than wall. Target
creature becomes that type untill end of turn.
If an opponent plays a spell or ability that can target a Flagbearer
play, the opponent chooses at least one flagbearer.
With a flagbearer in play, use Unnatural Selection to switch its type
another type (anything other than flagbearer). This makes the
flagbearer an illegal target and the opponent must still target a
flagbearer. We know the famous equation:
+ illegal target = discard with no effect
Tell me if this works!
