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

Serenity:
This one's for Tristan! Now…

Nezbitt:
Yes?

Serenity:
(thinking) As Joey and Yugi would say, "I have to trust my cards."

Duke:
Serenity, you already know everything you need to in order to beat this guy!

Serenity:
Right! (thinking) I just have to remember everything Tristan taught me that day… [Flashback to her and Tristan's Duel Monsters strategy talk on the train] So I have to sacrifice my weak monster to summon a stronger one! Well… That means if I want to summon the strong monster in my hand, I have to get rid of my weaker Lady Panther, first! Maybe this game isn't so tough after all! So here goes… I sacrifice my Lady Panther so I can summon Marie the Fallen One! Good!

Duke:
(thinking) I hope Serenity's getting the hang of this, 'cause if she messes this up now, Nezbitt will win the duel in his next turn!

Serenity:
(thinking) I've got the monsters I want… Now I need that Polymerization card so I can fuse them together!

Goddess with the Third Eye:
Serenity.

Serenity:
Was that you?

Goddess with the Third Eye:
Fear not, Serenity. As your Deck Master, I carry with me a very special ability. The power of fusion. I have the ability to combine two or more of your monsters together without the need for a Polymerization card. But, you must discard one magic card in order to activate my ability.

Serenity:
Okay, now feast your eyes on this little number, Nezbitt! First I'll dispose of this magic card, so then I can activate the special ability of my Deck Master!

Goddess with the Third Eye:
Fusion vision…go!

Serenity:
Goddess with the Third Eye, fuse together Marie the Fallen One and The Forgiving Maiden to form… St. Joan!

Nezbitt:
Impressive. But I'm afraid your monster isn't powerful enough to take me on. [Tristan's Command Angel glows, raising St. Joan's attack points by 400] What's going on? This can't be!

Duke:
Awesome! Command Angel's special power kicked in! It raised the strength of every fairy monster on the field, including St. Joan!

Serenity:
Thanks to Tristan's monster card, we can still do this!

Tea:
Now her St. Joan has 3200 attack points.

Yugi:
Yeah, but his Perfect Machine King still has more points. St. Joan needs another power boost!
