A question regarding [Standstill](http://gatherer.wizards.com/Pages/Search/Default.aspx?name=%2b%5bStandstill%5d); I have [Phyrexian Tyranny](http://gatherer.wizards.com/Pages/Search/Default.aspx?name=%2b%5bPhyrexian%20Tyranny%5d) on the table and we both have 2 life left. I play Standstill and immediately play an instant so that my fellow opponent would have to draw 3 cards, lose life and die. But, as I play Standstill my opponent also immediately plays an instant. Who draws the cards and loses?
