Chromatic Sphere appeared first in Invasion and
later in Mirrodin. The first was a
color-intensive limited format where it was
often quite reasonable to get a one-time color
for a kicker cost or splashed card; the second
was an artifact-heavy format where you didn't
always need quite as much color fixing in
general. Even when Fifth Dawn's five-color theme
was added to the situation, it was a little
overshadowed by the likes of Pentad Prism.
Still, there is always a place, somewhere, for
color fixing, and Chromatic Sphere also happens
to come in at a flexible cost, while synergizing
with anything that cares about artifacts going
to graveyards.
Today's card of the day is Chromatic Sphere
which is a one mana artifact that taps for one
to give you one mana of any color and you draw a
card. This is a fairly average color fixer
that costs two mana in one or two turns to give
one mana and a card. Other similar cards
exist and it can potentially be useful in a deck
that takes advantage of the sacrifice, but it is
mediocre at best as other options are available
depending on the build. Manamorphose,
Prophectic Prism, and Terrarion are potentially
stronger options that should be considered over
Chromatic Sphere, Chromatic Star, or Barbed
Sextant.
Well, it fixes mana and a cantrip for 2 mana. At
this point, there's better options. Manamorphose
if you're running green or red. It's decent in
limited, but otherwise, forgettable fodder that
will (and should) be relegated to wherever you
place jank commons.
