Syl, Unfocused Sorceress

When Syl, Unfocused Sorceress enters the
battlefield from it's owner's hand, put eight
casting counters on it.
{t}: Remove a casting counter from Syl.
{x}, {t}: Counter target spell with mana value X,
where X is equal to the number of casting
counters on Syl. Exile Syl, Unfocused Sorceress.
I've got it this time.
