Forget the potential 5/5 for 2U for a moment.
Let's look at what this thing does when it's not
a creature. First, it's a free scry 1 every
turn. And a very timely scry 1, since it comes
right before your draw for the turn. This
effectively lets you try for double or nothing
on every draw, and gives you a chance to rebuff
cards you don't want to draw. That alone
improves your odds of winning as the game goes
on, as you have a much better chance of "topdecking
like a champ".
Then, there's the activated ability. Usually,
abilities like this that let a creature go
unblocked are somehow tied to the power of the
creature they target-- ether by restricted on
what they can target (Goblin Tunneler) or cost
appropriately (Minamo Sightbender). Thassa has
no such restriction, and Worldspine Wurms can be
made unblockable as easily as Signal Pests.
There's also no limit on how many times in a
turn you can use her ability, besides your
available mana and supply of legal targets,
making alpha strikes quite fearsome indeed.
And if your devotion to blue is great enough,
one of the creature she can exempt from blocking
is herself-- an indestructible 5/5 who will no
doubt end the game in short order. Although
given her other abilities, splashing her into an
otherwise non-blue deck seems perfectly
sensible. I suppose it makes sense that the Blue
deity is the one that's most "splashable".
Thassa would be great if she offered only a
repeatable, cost-free Eyes of the Watcher.
Thassa would be great if she offered only a way
to make hordes of saboteur creatures unblockable.
Thassa would be great if she offered only a
cheap, almost-impossible-to-remove late-game
threat. Offering all three on one card is truly
divine. Each of Theros' gods is a flagship for
their color and will have an impact at some
point; Thassa has done so early, and so truly
deserves her space on our Top Ten list.
And yeah, she probably is a little jarring if
your memory of playing blue decks is "No, no,
no, no, no, no, no, no, dragon, win." This way
is more fun. For everyone. Try it.
The number five card of the year is Thassa, God
of the Sea which is a three mana Blue that is
Indestructible, a 5/5 creature with devotion of
five or more, grants Scry 1 at the beginning of
each of your upkeeps, and for two mana makes a
target creature you control unblockable until
end of turn. This is a very powerful card and
encourages an aggressive Blue build that
controls the draw each turn and regularly
provides unblockable damage. With devotion the
indestructible 5/5 is a great choice for the
unblockable effect and is well supported by
Phantom Warrior and Deathcult Rogue as they are
also unblockable and have two Blue mana symbols
in their casting costs for devotion. Overall
this is a card that can be a serious threat with
mono-Blue creatures and will be popular for
quite some time.
In Limited the unblockable and Scry effects
are more than enough reason to include this even
if Blue is not the primary color in the build.
With a strong Blue pool, particularly if it is
evasion based, this should win just about any
game it appears in for the consistent advantages
it offers. Scry every turn to build into
devotion and then attacking for at least five
that can't be blocked equals a short game.
An easy first pick in Booster and well worth
working into a Sealed deck even if Blue is only
moderately strong.
Thassa, God of the Sea is one of the best blue
Creature Enchantment cards ever made in the MTG
world. Why is Thassa so darn good? I would have
to say that her mana cost makes her more
dangerous than all of the other gods. 3 mana for
an indestructible 5/5 is just silly. The most
efficient part of Thassa’s game is her ability
to Scry. This ability will help players ditch
cards that they don’t need and help them get
through their deck faster! Her next ability is
what actually wins games. Thassa, God of the Sea
is the only god with built in evasion. She can
make herself unblock able or she can make your
other creatures unblock able. Mix all of these
abilities together and then throw in a Bident of
Thassa and you have the ingredients for a
migraine.
