Yami Yugi and Kaiba in “Unfinished Business”

Now what was that you were saying about your Egyptian God card being stronger than mine? Take a close look, Kaiba. Our monsters are even now.

Too bad your monster's effect is only temporary, Yugi. Once this turn is over, Obelisk will have all of his power back!

Perhaps, but I've still prevented you from attacking me this turn, Kaiba.

Stalling for time is a sign of weakness, Yugi! You're obviously desperate! Now it's my move! So stand back! I play two cards, both facedown! That ends my turn.

Very well. It's my move! Sorry, Kaiba, but since I'm now holding three cards, Slifer's attack points rise to 3,000!

But now that your turn is over, Obelisk regains its full strength! So your monster is weaker again!

Not quite, Kaiba! Observe my facedown card, Pot of Greed! Thanks to the effect of this magic card, I can now draw two more cards from my deck. And you know what that means, Slifer's attack points now rise to 5,000! More than enough to take down your Obelisk, and wipe out your Life Points, Kaiba! Now, my dragon, ATTACK!
