Testing a New Deck

With recent events, Ryan was in his room in the Obelisk Blue Boys Dorm.
He had just created a Disaster Dragon deck and needed someone to duel in order to figure out it's weaknesses and considering what happened during Syrus' promotion duel, he determined Missy would be the best target.
'Let's see how she fares against it.' He thought.
Ryan headed to the Obelisk Blue girl's dorm.
Ms. Fontaine was outside, guarding the entrance.
"Hello, Ms. Fontaine." He kindly greeted the girl dorm's headmaster. "I'm here to challenge Missy to a duel."
"I'll let her know you're here." Ms. Fontaine went inside to get Missy.
Missy came outside a few minutes later.
"What do you want?" She angrily demanded.
"Challenge you to a duel obviously." Ryan retorted.
"A duel, huh?" She asked, before smirking. "You got a deal." 
Missy followed him and the two activated their duel disks.
"Since I issued the challenge, you can go first." Ryan stated.
