Yugioh GX Synchro Style/Chapter 3: A Duel in Love

The next morning, all the students were in class as Dr. Crowler asked Alexis to go over the different card types.
"Alexis, can you tell the class about the different categories of Duel Monster cards." Dr. Crowler instructed.
"Of course Dr. Crowler." Alexis nodded and then stood up. "Duel Monster cards are divided into Normal Monster cards, Fusion Monster cards, Ritual Monster cards, Effect Monster cards, Trap cards and Spell cards. Trap cards are divided into Normal traps, Counter traps and Continuous traps. Spell cards are divided into Normal spells, Continuous spell, Equip spells, Quick-Play spells, Ritual spells and Field spells." After answering Crowler's question, she sat back down.
"Well done, I expected nothing else from one of my Blues." He praised Alexis. 
"Now, who should be questioned next?" Crowler asked, looking around the room. His eyes then locked on Syrus.
"Syrus Truesdale, tell the class about a field spell."
"Uh, the field spell...is the thing that." Syrus stammered.
