Hi all,

I tried to look through the forums to find an answer but wasn't able to find an answer to my question, so I'm sorry if this is somewhere already. I was just wondering how I can search for spells with (X) in their mana costs (if that is possible). I know I can search for "X damage" in the Rules Text, but that necessitates that I know the exact wording on the card and catches a bunch of non-X spells.

Thanks for any help!

Afaik, you cant search for cards with X in their casting cost (unless the casting cost is only X, like walking ballista) But with that option you also get every card that has Mana costs of zero (i.E. Ornithopter).
With Search option "Rules Text" and {X}, you will find every card with an X cost in their Rules text, not just Burn Spells.

Edit: However, with that option, you will also find cards like Ghalta, Primal Hunger because he has an X in its Rules Text.

If you need advanced searching, the answer is always to use scryfall:
