The important thing to note here is that you have immediate priority after you put a spell on the stack, so you have first dibs at responding to your own spells and abilities
As for the Mythic Invitational itself, I would call the event a modest success
That said, buying specific foil singles is almost always more efficient if you know exactly which cards you want
As a note, Ezio, Blade of Vengeance can only be found in the Assassins Creed Starter Kit
