Fork and a Fireball

[EricSS]

Ok, the group know it all is telling me that using Fork on a Fireball is pointless because the x factor on the fork spell will = 0. I did some research and believe that that is wrong. Can anyone confirm this?

You are correct. http://gatherer.wizards.com/pages/card/Details.aspx?multiverseid=1294

Relevant part : 10/4/2004 Forking a spell with an X in the cost requires you to use the same X value.

107.3a. (http://yawgatog.com/resources/magic-rules/#R1073a) ... While a spell is on the stack, any X in its mana cost equals the announced value. ...

706.9. (http://yawgatog.com/resources/magic-rules/#R7069) ... A copy of a spell or ability copies both the characteristics of the spell or ability and all decisions made for it, including modes, targets, the value of X, and additional or alternative costs. ...

X is defined while a spell or ability is on the stack, and 0 anywhere else.

The value of X is copyable, so copies of spells or abilities will copy the value of X.
