I find it kind of funny in a way that the
references to Theseus' story are spread out
across about eight Theros cards. It's probably a
good thing, as it's probably not really possible
or reasonable to cram any one myth onto just one
card, but it is noticeable. While Labyrinth
Champion is arguably not the most powerful
example of the heroic ability word, there are
lots of creatures in Theros and nearby sets that
it can kill outright. Extra value from a card
you were playing anyway is always a good thing,
especially when you add it to types of cards
that traditionally have an element of risk
associated with them like Auras and Giant Growth
effects.
Today's card of the day is Labyrinth Champion
which is a four mana Red
2/2 with the Heroic ability of dealing two
damage to target creature or player whenever you
cast a spell that targets it. This is a solid
effect and easily supported with combat tricks
or auras, but the four in the mana cost is a big
drawback in any Constructed format and isn't
helped by the low power and toughness. The
potential for reusable burn will have this see
some play, particularly in Heroic themes, but
outside of that or a specific combo it isn't
likely to be popular.
In Limited this can be a very dangerous card
which makes it an easy first pick in Booster
with the wide range of spells available to
target it for repeated use of the burn effect.
The single Red in the casting cost allows ease
of use in multicolor builds and there is little
reason not to include it whenever Red is present
in your Sealed deck.
Labyrinth Champion is a human warrior that has
conquered the Labyrinth. You are probably
wondering how a 2/2, WITHOUT first strike or any
evasion skills could conquer anything. Well, he
used his HEROIC ability. Cast a spell that
targets Labyrinth Champion and L.C. does 2
damage to target creature or player. At first
glance this sounds amazing, but then you look at
the mana cost. 4 mana for a 2/2 that does
nothing on its own. Labyrinth Champion is a card
that is begging to be broken. Until that time,
it is a below average creature.
