At the start of the Battle Phase: For the rest of this turn after this card resolves, Spell/Trap Cards, and their effects, cannot be activated. Cards and effects cannot be activated in response to this card's activation.
Eevee, A quickplay spell card can not be used the turn you set it just like a trap card. But you can use it from your hand during the battle phase. In this case, if you want to rush your opponent with your monsters, you can active it from your hand once you start your battle phase.
