What can giving a creature you control
protection from a color do? It can fizzle any
colored spell your opponent plays targeting that
creature. It can remove unwanted Auras, like
Lust for War or Narcolepsy. It can severely
restrict your opponent's ability to block. It
can allow you to block a creature that would
otherwise kill said blocker. Or it can prevent
some damage to it, say from a Volcanic Fallout
or Disaster Radius. So basically, it will
counteract one spell of your opponents against a
creature you control, or allow that creature to
deal additional damage to your opponent.
Emerge Unscathed is pretty straightforward, as
far as instants which ambush your opponent and
completely mess up their plans can be
straightforward. I really like that you can get
two uses out of it, as one instance of this
effect is not always enough to break a
wall-heavy or token-heavy standoff. Just watch
out for Riftsweeper.
Today's card of the day is Emerge Unscathed
which can give one creature protection from a
color then does the same on the following turn.
Generally this would be used as a response to
removal on your opponent's turn then a likely
unblockable attack on your turn. A nice
trick, especially in an Exalted deck, and gives
a good option for White in dealing with Red,
Black, or Blue targeted spells.
For Limited most opponents will likely be
running multiple colors and some colorless, but
this is still a good response as it is unlikely
two different colors will be used as removal in
the same turn. Offensively it will be more
difficult to get a clear shot, but avoiding even
one specific blocker can be a big advantage.
Not the highest draft priority, but something to
get when in your colors after more critical
spells. In Sealed this is a safe choice to
flesh out the White half of a deck, but can be a
little lacking as a topdeck in a losing
position.
