Yu-Gi-Oh!, Season 4: Waking with Dragons

Pharaoh:
[horrified shock] What's that?!

Tea:
I've got one word: nasty!

Tristan:
Here's four: I'm gonna be sick.

Pharaoh:
For the last time, what is that thing?!

Rafael:
I told you-- when Eatos goes to the graveyard, this monster is summoned to the field in its place. So say hello to my Guardian Dreadsycthe!

Pharaoh:
Hello and goodbye. It's no match for my dragon!

Rafael:
It will be. First, I'll boost its strength with my Reaper Scythe magic card. Now, for the best part, thanks to its new weapon, my Guardian of darkness gains 500 attack points for every monster in my graveyard.

Pharaoh:
But why? I thought you despised having monsters in your graveyard!

Rafael:
But I despise you even more, so what's a few monsters in the grave if it means destroying you forever? And with only 500 life points left, you won't last long.
