My main complaint about this card is not even gameplay related - it's that the flavor text of
her "night" side implies that that side of the
card could (should?) be red! She's driven by
emotion and/or instinct, after all. Still, she
has aggressively costed combat statistics, and
while her stat upgrade is minor for the cost of
a card, this set does feature the return of the
madness keyword. I assume this will be the major
niche that she occupies, though I do note that
her ability doesn't specify any particular type
of thing to discard, and that the new Eldrazi
don't automatically shuffle themselves back into
your library the way Emrakul does.
In any other set, this would "just" be a 3/2
flyer for 1B and "discard a card". Not bad at
all, since flying aggro is a powerful archetype
and black is pretty good at getting things back
from the 'yard. But here? This is the realm of
Madness! The Heir's real inheritance is the
ability to cheat out a cheap spell and be
upgraded in the process. It's unlikely then,
that you'll just plunk this down on Turn Two and
pitch a card immediately. More likely, you'll
wait until Turn Three to play a Madness card and
then swing for three, or perhaps even keep it
untransformed until you draw what you need.
After all,t hat "once per turn" clause isn't so
you can't transform it repeatedly, it's so you
can only pitch one card before it flips into
something that can no longer pitch cards!
So here's an interesting thing. Madness enabler
and a transformer. being able to flip it at any
time with a discard gives it points, so you can
at the very least turn a fairly obvious combat
trick, maybe even pull a madness cast at instant
speed at the same time. A lot of people won't
think of it, but ninjutsu (remember that
mechanic?) decks will love this card.
