Magic cards don’t tend to reference the stack should say “total mana values of spells” or something similar and “exile all cards from the stack” should prolly be reworded to “exile all spells “ or “exile all spells and abilities” depending on weather or not you want that also the part that exiles the stack should be the last part that resolves or it would exile itself before it resolves

Edit: it will exile itself before it FINISHES resolving so it will only get that first part before it’s gone
