Team-Buster decks get a much-needed hand with Blank Page.
At first glance, this card's utility seems somewhat limited. But then I though of my Slug deck, and how I like to use the Daydreaming Mission to power my Six-Tails. 2 Daydreaming + Blank Page = I could boot the Nine-Tails off its team if I wanted to. Add to this all the other wonderful Team-Busting effects Wind's been getting lately, and you've got your theme deck.
The other great part about this Mission? No Hand Cost. On turn 1. There's your utility. Have fun with this.
