William smiled at the young lady, she reminded him of his own mother, nothing like his younger sister also starting in first year, she was a waste about and never really felt dedicated to anything despite being an incredibly prodigious magus and his father had told him he had to give her an Arcana but he never said which one. 

"Saber huh? Well I like you. And well I don't really like the Saber class that much, magic resistance proved a bitch in the tournament. I'll let you use your one shot summon, to summon any servant you like. And if you can managed to get Caster to use an NP, I'll give you the Saber card to allow you to keep your servant. If you beat me, ha, or figure out Casters name, I'll also give you another Arcana minor, not including Caster, to either give to someone else or summon your servant in an alternate suitable class."

William stood up and downed his beer. Pludging Gram into the ground.
"So what do you say Ms Alysis, Alysis Woe, a voice to be heard must be powerful and try and stand out amongst the whispers." William smiled, he liked this girl, how much depends on her answer.
