Yu-Gi-Oh!, Season 3: Enter the Shadow Realm

Kaiba:
I win!

Yami-Yugi:
I wouldn't be so sure of that. Remember, I still have one facedown card left. Kaiba, you're done!

Kaiba:
You LIE!

Yami-Yugi:
As you will soon see, I've been destined to defeat you for 5,000 years!

Kaiba:
Enough! My Blue-Eyes Ultimate Dragon cannot be stopped, Yugi!

Yami-Yugi:
I'm afraid you're wrong! But I'll let my card speak for itself! So I play this, my De-Fusion card! This magic card splits up your Blue-Eyes Ultimate Dragon into the three original dragons you fused to form it, thus stopping your attack!

Kaiba:
(thinking) No! I need my Ultimate Dragon to win the duel! This can't be happening!

Yami-Yugi:
Now, Kaiba, you have three dragons on the field instead of one! And since my Dark Paladin receives 500 attack points for every dragon on the field, he's now the strongest monster in play! Now it's time for my final move!

Kaiba:
Just go.

Yami-Yugi:
With pleasure, Kaiba! All right, the card in my hand will conquer the darkness that now surrounds your heart! So I play my final magic card-- Diffusion Wave-Motion! You're finished! All I have to do is give up 1,000 Life Points and this magic card will inhance the attack capabilities of my Dark Paladin! Now my monster can attack all three of your Blue-Eyes White Dragons at once!

Kaiba:
(thinking) His Dark Paladin has enough power to wipe out my dragons AND my Life Points!

Yami-Yugi:
This duel is over!

Kaiba:
Yugi, I will not be defeated at my own tournament!!!

Yami-Yugi:
Kaiba, you're too late! Dark Paladin, ATTACK! [Dark Paladin attacks and destroys Kaiba's three dragons and his Life Points drop down to zero] You lose, Kaiba! I told you, your hatred and your lust for power would never prevail. (thinking) I did it! But my toughest battle is still ahead… when I face Marik in the final duel!
