How it works
Declare any creature as an attacker, attacking an opponent unable to block it.
When the creature is unblocked, activate Phage's ninjutsu ability by paying 2 and returning the unblocked creature to your hand, putting Phage onto the battlefield tapped and attacking.
Phage enters the battlefield, however you cannot lose the game due to Platinum Angel.
Deal combat damage with Phage.
Phage triggers, causing the opponent to lose the game.
