As a creature, it's a worse Centaur Courser. As
a combat trick, it's a worse Giant Growth.
Neither of those cards has been relevant in
Standard so far, so slightly worse versions
don't have much to hope for.
Then again, if I really need a creature and I
draw Giant Growth, I lose. Slaughterhorn doesn't
have that problem. The whole value here, and of
Bloodrush in general, is that you choose what
you need based on the state of your current
field presence. I think I'd still rather have
one good card than my choice of two bad ones,
but at least Slaughterhorn isn't completely
useless. I do hear rumors that the next Core Set
will have some Beast tribal...
This card is the very definition of solid. As a
creature, it's nothing too spectacular, but
three power for three mana is perfectly
acceptable and fights decently on offense and
defense. Its bloodrush ability looks like Giant
Growth, but naturally lacks the subtlety and
versatility of its famous ancestor; still,
giving something +3 power for one mana can lead
to blowouts. Having the option for either is
what makes this card good.
Today's card of the day is Slaughterhorn which
is a three mana Green 3/2 or for one Green it
can be discarded for Bloodrush to give +3/+2 to
target attacking creature until end of turn.
This is a somewhat under-appreciated choice for
an aggressive Green deck as it works as a less
flexible Giant Growth on the offensive or a 3/2
as needed. The choice gives it value in multiple
builds and it is likely to be played across
formats as a sleeper threat for quite some time.
In Limited this is often a Giant Growth which is
excellent in the format, or in a topdeck
situation it is a decent defense by placing
three power in the path of any attacker.
Even having a 3/2 against a weak field position
is playable if the situation calls for it and
with just one Green in the cost every Green deck
can benefit from including this. The three
power is also likely to trigger Evolve which
adds priority to drafting this in Sealed and
Booster for Simic cards. With multiple
applications there is no drawback to including
this in every Sealed with Green mana and
drafting early in Booster.
