Annihilator 2 (Whenever this creature attacks, defending player sacrifices two permanents.)
Official Rulings for Artisan of Kozilek
6/15/2010 : If a creature with annihilator is attacking a planeswalker, and the defending player chooses to sacrifice that planeswalker, the attacking creature continues to attack. It may be blocked. If it isn't blocked, it simply won't deal combat damage to anything.
6/15/2010 : In a Two-Headed Giant game, the controller of an attacking creature with annihilator chooses which of the defending players is affected by the ability. Only that player sacrifices permanents. The choice is made as the ability resolves; once a player is chosen, it's too late for anyone to respond.
