Obviously, there are a lot of spells this is
useless against. But we're still coming off the
multicolor enriched block of Ravnica, so there
are quite a few spells ut there that are white
or green. Good spells. Of course, it's a
sideboard card in Constructed and Limited, and
in Limited it's probably not even worth bringng
in unless you're facing the R/G guy, but it is
still a hard counter for 1U
Blue often
gets hosed on color hosers, but I think this one
is quite decent. Finally, instead of getting
some color hoser that does something blue's not
normally known for, they get a hoser that's just
a counterspell. That's right up blue's alley, as
it were. Against many decks, this will simply be
a hard counter for 2 mana. That's definitely
good news. Blue can have a lot of trouble
dealing with an early fatty, and Flashfreeze is
an excellent cheap counter to help keep them off
the table. It's decent in limited, too.
Red/Green is a popular combination in Coldsnap
limited, and this becomes a very strong spell
while you wait for your opponent's big bomb.
There's only so many cards in the format that
can deal with Rimescale Dragon, and this is one
of them.
