This card is going to be highly traded. Angels
appeal to lots of casual players and this one
has an awesome ability. I'm not sure you can
expect to see a lot of these in competitive
play, but it's possible that control players
will enlist this angel to do battle for them.
There are lots of neat combat tricks that a card
of this caliber lends itself to.
For six mana, cards need to pretty much win you
the game. This card does exactly that. With
this, your opponent can't effectively block
anything, because suddenly "trading" becomes
"I'll trade my 4/4 for it and your 3/3". And if
it's untapped, your opponent can't really hope
to kill anything and get away with it. In
Limited, if you untap with this in play, and you
don't win, then either your opponent had you
long before the Valkyrie resolved, or you
weren't using it right.
Valkyrie - Angels always seem to get some of the
best combinations of abilities. Rarely do they
end up at odds with thsemselves. The Valkyrie is
a fine example. Vigilance and a tapping ability
are always worth examining closer and this one
is great. It can steal your opponent's creatures
and it can save your own. It also happens to be
big and damaging. Expect to be dealing with this
one in Standard for the next two years.
