Countershpiel

When you cast this card and it is on the stack,
you can target target spell on the
aforementioned stack. Counter (which is to
say, stop that card from being played and send
it to the graveyard) that targeted spell if it has
more than twenty words printed on it, not
counting the words "Magic", "the", "Gathering",
and "Deckmaster" that appear on the back of
most cards.
