What is storm count for a storm spell that was cast as part of the resolution of Villainous Wealth?
Here’s the situation: my friend casts [[Villainous Wealth]] targeting me for X=8 (note that this was the FIRST spell he cast in the turn). He flips 5 spells total, with the final being [[Empty the warrens]], and chooses to cast all of them. He chooses to have the Empty the Warrens go on the stack last, hoping to maximize Storm.
Here’s the question: Is the storm count for Warrens 1 or 5? Hypothetically, if all spells being cast as part of the resolution of VW are being cast simultaneously, the only spell cast “before” warrens is VW, regardless of resolution order? Or does Storm count somehow go up with each spell selected in order?
Would love a reference to the specific rule(s) in the comprehensive rules that contains the answer, as this was a bit of a debate at the table.
