I get a total "At the Mountains of Madness" vibe
from this card, and it's a good thing in this
case! I'm not sure how much of a cost returning
exiled cards to their graveyard is going to turn
out to be. On the one hand, there are decks that
use their graveyard basically like a second
hand, but you won't be playing against those
every game. It also has some interesting
dimensions for multiplayer and Commander, where
you are likely to have more opponents with
exiled cards to target, plus the ability to use
the return ability politically to benefit
someone you want to.
Today's card of the day is Ulamog's Nullifier
which is a four mana Black and Blue 2/3 with
Devoid, Flash, and Flying plus it can it can
counter target spell by returning two opposing
cards from exile to grave. This card
requires some support to exile cards and both
Blue and Black mana sources, keeping it more in
line with Dimir or perhaps Esper, Grixis, or
even Sultai designs. The creature itself
is not bad, but not remarkable either and does
work well as a surprise blocker against a 2/2
with Flying. The conditional counter is
situational, but useful as it is attached to a
creature for one mana over a Cancel.
Timing both at the same time is unlikely unless
the opponent makes an error during the attack
step, so that weakens the card slightly.
Overall this is a solid card with different
potential applications and may see play in
Standard or control decks in Modern.
In Limited this is a very effective use of mana
on the opponent's turn that can block or counter
a spell then offer an evasive creature on the
next turn. A great second pick in Booster
that can be splashed if needed and a good bridge
in Sealed if both Blue and Black appear strong.
