Ah yes, a card for
the kiddies to end the week. At 9 to cast,
it's much too high to see any play in most
decks, because one of four things will
have happened:
1) The game is
already over.
2) They've
stripped it from your hand.
3) They've got a
couple of counterspells ready, or
4) They've got
control (either through Ensnaring Bridge or
having a Wrath in hand).
In limited,
however, the 6 Wurms you will get will come up
eventually. And they will cause serious
problems with your opponent's math.
Constructed: 1.5
Limited: 4
