Kaiba and Yami Yugi in “Unfinished Business”

Now, Obelisk, destroy his Slifer! It's over! Your Egyptian God card is ancient history! What?! Your Slifer should've been destroyed!

Well, it would have been had I not stopped Obelisk from attacking, Kaiba.

What?!

And I have you to thank for giving me the ability to protect my Egyptian God card from yours, for that task was only possible thanks to a trap card that you played! When you activated your Power Balance card, I had to place three cards in my graveyard… including this! Recognize it? It's a useful monster card known as Electromagnetic Turtle. And it has quite a unique special ability. When this monster is sent to the graveyard, it leaves a small electrode attached to one of my monsters, in this case, Slifer!

And it lets you stop our battle before Slifer was unlucky enough to collide with Obelisk?

Well, I see you did your homework, Kaiba. Now I place this card facedown.
