This build features a lot of searchability. Giant Rat can retrieve a lot of cards, such as Injection Fairy Lily and Pyramid Turtle. Pyramid Turtle can fetch some powerful options. The deck also uses a small warrior toolbox. There are some strong anti-meta cards as well. I'm fond of the side deck; there's a selection of cards I chose for dealing with decks that give me a lot of trouble.
Edit: I took out the Solemns, they were conflicting with Lily too much. In their place I now run 1 Sakuretsu Armor, 1 Dust Tornado, and 1 more RotA. I feel that the main deck and the side deck are working better as a result.
