Ok so last game I was playing with a friend, I had out Reya Dawnbringer and Shadowborn Demon on the field at the end beginning of my upkeep. I tried to sacrifice my shadowborn demon and then resurrect him with reya dawnbringer in the same upkeep step, is this legal or does the stack order not allow this?
So my friend was playing with volatile rig and his opponent used ghostly prison. Since ghostly prison is on the field does that mean volatile rig is unable to attack or should he be forced to pay the mana and attack?
Please link the rulings.
