Is there something specific that you can type to search for cards with a cost that includes X, where the X affects the ability?

I'm getting no results in the card cost search, and an X in Rules Text turns up any card which features an X in that box, even if it's part of a word.

Not sure if this will get you closer to what you want, but search for rules text containing "{X}". The brackets denote a cost symbol. For example, if you wanted all cards whose rules text includes a cost of 2 and a Blue, you'd search for "{2}{u}". For something like green phyrexian mana, use "{gp}". For stuff like Tower Above, it's "{2g}".

I will try that. Thanks. :)

This only finds it in the rules text, not the casting cost, unfortunately. So it won't find e.g. Fireball.

Yeah, I know. I figured it would help locate cards where the ability is affected by the X, though.
