The real key to this card's strength is that the
two lands come into play untapped. So you spend
three mana, sack one of the lands you tapped,
and get two untapped lands, for a net cost of
only one mana and one land. And of course, it's
an instant, so in Zendikar you can trigger
landfall abilities at instant speed with it. To
say nothing of the fact that it accelerates your
mana, and gets you colors of mana you may not
have had, and thins lands out of your deck to
increase the odds of drawing a spell...
I remember seeing the first version of this
card, from Tempest, and thinking it was one of
the most powerful multicolor enablers of all
time. It still is, but it's become so much more
than that over the years. Still, I never thought
I'd see the day when it became a combat trick
(thanks to landfall) - make the most of it!
Constructed: One of the best land search cards
made. And combine it with the Landfull ablility
makes it sick. The good Landfall creatures are
not really in green, except Lotus Cobra.
Casual & Multiplayer: Good for any crazy 5-color
deck.
Limited: Good to get ahead on mana, but green is
not the strongest color for limited. But if you
are going more than 3 colors than this card is a
must. Works great with Lotus Cobra.
Today's card of the day is Harrow, one of the
best mana acceleration cards available to modern
formats. To some it may not seem a big advantage
trading one land for two and using three mana
and one card to do so, but this is not the case.
As an example on turn three (without any other
mana source) this can be played, tapping three
lands and sacrificing one of the tapped lands to
gain two untapped lands. The net result is an
additional land in play (so no loss of card
advantage) and one mana spent. One mana to gain
an extra turn's worth of land on the battlefield
is almost pure advantage and should be
considered for a large variety of decks.
For Constructed, Casual, and Multiplayer this
a is a top of the line source of speed and can
be played in any deck with a decent supply of
basic lands and Green mana. Domain and Landfall
themes really benefit from Harrow and even if
played later in the game it removes lands from
the library improving your topdeck options.
With Limited this should probably find a home
in almost every Sealed deck and certainly all of
the ones using Green mana. The basic land
restriction is not an issue in this format and
many cards also have Landfall. With Booster this
should be an early pick and second only to major
bombs and excellent removal.
