I bought 4 boxes and expensive singles ages ago, and it was frustrating to let them just sleep in my shelf. So I built this.
I guess it's considered the "most meta" Charlotte deck to be, and it's probably the best stall deck in all Weiss Schwarz.
Just wait for the best moment to play your lv.1 combo (you usually wont be able to pull it of the turn you hit lv.1), get your backups to save your 1/1 and wait for lv.3. Then between your Yuu memory anti-burn, Nao anti-front, and Yusa 12k5+ scry, the rare damage that will get through your fortress will be swept away by your costless Misa heals.
Just remember to always brainstorm to maximize compression and maintain hand size before lv.3, and try your best to have at least 2 backups in hand at any time.
Oh, and this deck is weak against bounce and restanders that don't need to reverse. It takes care of every other threat.
