Today's card is a mill effect, that has a chance
of letting you draw cards. I've made my thoughts
about mill cards quite clear, but this one's
added effect gives us reason to think.
In Blue, this is outclassed on both fronts. For
a mill spell, Mind Sculpt mills more for less
mana and still isn't good enough to play. And
for a draw spell, five mana for an unspecified
number of cards just isn't reliable enough.
Combined with Totally Lost, it might work, but
that requires ten mana.
Black, however, might find a use for it. It's a
spell that can draw you cards, without costing
you life, and can also give you a nice juicy
target for a re-animator spell. The randomness
still kills it though, even if you are likely to
get around two cards given some reasonable
assumptions about your opponent's deck.
As library-attacking cards go, this is not
quite the most efficient. Everybody likes
getting to draw cards, though, which makes it a
little better as a package. If you just want to
attack the library, there are more impactful
ways to do so; if you just want to draw cards,
there are more reliable ways to do that. But
when you have the chance of doing both at the
same time, Coerced Confession becomes more of a
contender some of the time (watch out for "planeswalker
control" and similar decks).
Today's card of the day is Coerced Confession
which is a five mana Blue or Black sorcery that
has target player mill four cards and you draw a
card for each creature send to the graveyard by
the effect. The cost on this is fairly high and
even if played on yourself to fill the graveyard
and gain some cards in hand it is not completely
reliable on draw power. There aren't a
huge number of similar options in Standard with
Thought Scour being the best. Overall it
is probably better to run other cards that focus
on drawing or milling, but if you need one that
can possibly do both this is an option if a weak
one.
In Limited the number of creatures in most decks
along with the smaller deck size and fewer
options for drawing cards makes this a bit
better.
The cost is manageable and if supported Dimir
can manage to mill in the format, though it is
still unlikely. Worth including in a theme
for Sealed and if drafting into it can be an
early pick in Booster as well.
Other decks shouldn't even consider playing this
as it is very specialized.
