Girl with Glasses in the kitchen/cafeteria area? Are they talking about Kotori? 

I also play MTG. ^_^; With a few fast-paced decks.

Gruul Zoo
Blue/Black Mill
Affinity Artifact Blue
Black/White Tokens

They're all modern though. I spent too much on Goyfs to invest in keeping up with Standard.

Not YGO. I used to have a YGO RPG lock down deck almost 10 years ago though. With Horus, etc.
