Apocalypse rare, Time Spiral "Timeshifted" reprint
1GUU: Creature - Snake
Flash (You may play this spell any time you could play an instant.)
When Mystic Snake comes into play, counter target spell.
Its fangs are in your flesh before its hiss leaves your ears.
Good GOD, this will be broken for Simic decks. It's a counterspell attached to a 2/2 essentially. It's almost a free card for you interms of card advantage because this guy doesn't cost you a card to counter a spell.
