Today's card of the day is Aetherling which is
a six mana Blue 4/5 with four activated effects.
For one Blue you can exile it until the
beginning of the next end step, which is
excellent for avoiding removal and triggering
comes into or leaves play abilities. The second
makes it unblockable until the end of turn for
one Blue which combines very well with the +1/-1
for each colorless. The fourth is -1/+1 for one
and can be combined with the exile effect for a
pseudo Vigilance to block nearly any threat. All
combined make this a very versatile and
dangerous threat in a control theme that can
afford the time and mana to utilize it. It
doesn't enter the game until fairly late and
requires a decent amount of mana to be
effective, but overall it will see play and be a
problem for many decks.
In Limited this is a serious bomb that can
easily win games by becoming unblockable and
pumping up with most of the untapped mana. It
can trigger Evolve repeatedly and has no real
weakness, aside from a slight reliance on Blue
mana keeping it from being splashable.
