You can only use the (1)st and (2)nd effect of this card’s name each once per turn.
(1) If this card is Normal or Special Summoned: You can add 1 monster from your Deck to your hand with a coin tossing effect, except “Goddess of Duality”.
(2) During your Main Phase: You can toss a coin and call it. If you call it right, the ATK of all face-up monsters you currently control become doubled until the end of this turn. If you call it wrong, send as many monsters you control as possible to the GY, and if you do, draw 1 card.
