Let's say I have a 2 power prowess creature such as
Seeker of the Way on the battlefield. If I want to hard counter someone's spell with
Stubborn Denial, and do so with another non-creature spell such as
Twin Bolt, am I correct in thinking that I wouldn't have to cast the
Twin Bolt first? Or would the order matter?
As I understand it, I would cast
Twin Bolt, activating prowess on
Seeker of the Way, and making it a 3/3. Then, in response to
Twin Bolt or after it resolves, I cast
Stubborn Denial making
Seeker of the Way a 4/4 by the time
Stubborn Denial resolves. However, it seems to me that the reverse would also work so long as I cast the second spell before the first resolves. By casting
Stubborn Denial first, I would boost
Seeker of the Way to a 3/3. Then casting
Twin Bolt before
Stubborn Denial resolves would make
Seeker of the Way a 4/4 by the time
Stubborn Denial resolves, thus resulting in hard counter. So both situations would be identical as long as the second instant were cast in response to the first. Is this thinking correct?
