Transforming Flourish

If you cast the spell and choose not to copy it, no opponent will get to copy it either.

If the exiled card has {X} in its mana cost, the destroyed permanent’s controller must choose 0 as the value of X when casting it without paying its mana cost.

If the spell requires targets, you choose the target of the original spell as you cast it. If you create a copy of the spell, you may choose new targets for the copy as you create that copy. Similarly, the opponent you chose to create a copy may choose new targets for that copy as it’s created. In other words, your opponent will know the targets of your original spell and your copy when choosing the new targets, if any, for their copy.
