Yo dawg, I heard you like burn decks

It's an interesting idea, but you'll need to tweak the wording a little - right now you've got a cross between a triggered ability and a replacement effect. I'd suggest something like:
>Whenever you cast an Instant or Sorcery spell, you may have ~ deal damage equal to that spell's mana value to any target. If you do, put that spell card into your graveyard *(it won't resolve)*.
It seems fun, but could be abusable with things like spells with alternate casting costs.
I'd considered that, and I think anything you pay for an X would go towards the burn effect in this case. The mana value of copied spells is 0, I believe, so you can't storm an opponent to death. I think it's tricky because you're right, the creature ability is triggered by casting a spell and the triggered ability essentially replaces the effect of that spell with the damage. I did intentionally not let it interact with creatures to avoid letting it be a board wipe.
I think X spells are fine - you're spending the mana anyway, so turning any X spell into a Blaze seems reasonable. I was more concerned about things like Force of Will, which becomes a "free" 5 damage to any target as long as you have a spell to target. Or casting a spell via Suspend or Foretell where you get to cheat on the mana cost. But maybe it would be interesting trying to build a deck around cards like that anyway.
I see. Maybe it would be better to say "deals damage equal to the amount of mana spent to cast that spell."
The mana cost and value of a copy are the same as the original.
They're not, look up mana value rules.
707.2: When copying an object, the copy acquires the copiable values of the original object's characteristics and, for an object on the stack, choices made when casting or activating it (mode, targets, the value of X, whether it was kicked, how it will affect multiple targets, and so on). The copiable values are the values derived from the text printed on the object (that text being name, mana cost, color indicator, card type, subtype, supertype, rules text, power, toughness, and/or loyalty), as modified by other copy effects, by its face-down status, and by "as . . . enters the battlefield" and "as . . . is turned face up" abilities that set power and toughness (and may also set additional characteristics). Other effects (including type-changing and text-changing effects), status, and counters are not copied.
So this is in reference to Circle Casting, or possibly Elven High Magic: [https://webcache.googleusercontent.com/search?q=cache:e9i4qUvSs8oJ:https://forgottenrealms.fandom.com/wiki/Elven\_high\_magic+&cd=1&hl=en&ct=clnk&gl=us](https://webcache.googleusercontent.com/search?q=cache:e9i4qUvSs8oJ:https://forgottenrealms.fandom.com/wiki/Elven_high_magic+&cd=1&hl=en&ct=clnk&gl=us) or [https://webcache.googleusercontent.com/search?q=cache:o1Hx09Jeek0J:https://www.realmshelps.net/magic/circle.shtml+&cd=2&hl=en&ct=clnk&gl=us](https://webcache.googleusercontent.com/search?q=cache:o1Hx09Jeek0J:https://www.realmshelps.net/magic/circle.shtml+&cd=2&hl=en&ct=clnk&gl=us)
It's a cool concept, and maybe something you could refine to to a cycle or series. I suggest the following changes:
Creature - Elf Wizard Circlecaster
Whenever you cast an Instant or Sorcery spell, you may have \~ deal damage equal to that spell's mana value to any target. If you do, put that spell card into your graveyard (it won't resolve). Copy this ability for every Circlecaster you control. Lose life equal to the number of times this ability resolves.
The Circle in its name is a reference to the circle of magi from the dragon age game series. I'm building a set based on that universe. Thank you for all of that information though.
