E.g.: SnT player Plays Sneak Attack and after paying 4 mana he has 1 untapped Volcanic Island and 1 Lous Petal left on board, and you have an active Knight. Then SnT play activates Sneak Attack by tapping Volcanic Island for R for the first time>>>
1.) >> you activate KotR at end of mainphase and bounce Emrakul with Karakas.
2.) >> you activate KotR at end of the beginning of combat step and bounce Emrakul with Karakas.
3.) >> you activate KotR in response to the annihilator trigger and bounce Emrakul with Karakas, then sacrifice 6 permanents.
If you follow Way 1.) your opponent activates SA with the Petal and brings in Emrakul again, then attacks you for 15 + annihilator.
If you follow Way 2.) your opponent activates SA with the Petal and brings in Emrakul just in the beginning of combat step, before declare attackers and attacks you for 15 + annihilator.
If you choose Way 3.) you only sacrifice 6 permanents and dont get dmg, but your opponent has Emrakul in his hand again and is going to kill you next turn.
So the best way is to tutor Maze of Ith in response to annihilator so emrakul dies at eot and you get no dmg, even that is an incredibly bad deal.
