Pretty sweet card. I kind of want the first ability to be removed, though - the only way you can really play around a deck built around this card is to be faster than it or to use discard. Allowing this to be countered might help broaden the number of deck types that are able to interact and have counterplay against this hypothetical combo deck, simply because this is the type of card that begs to an opponent "Counter me or you are probably dead", and most decks will probably only have one counterspell available anyway at most given turns.
