Cardfight!! Vanguard TCG - Battle Sister, Cocoa (EB05/015EN) - Extra Booster Pack 5: Celestial Valkyries

An ideal Oracle Think Tank, allowing the player a bit of control with chances of drawing trigger effects during battle, or certain cards otherwise.Like some other cards, it's even more effective when used with Goddess of Flower Divination, Sakuya, a card that returns all of the player's rear guards to his/her hand for additional use.
