Interesting. This could be either red or blue; I don't know if wild be printed as a genetic spell.

Think through the wording: How often is a spell you didn't cast this turn going to be a valid target? I think the answer is never. This should read "Copy target instant or sorcery spell you own."

okay, will make it blue.

Unless it's meant to be able to copy a card in your hand, or graveyard, or even sideboard as a wish?

oh will edit it to be clear

this is instead of in your graveyard, this way it can be used for instants and sorceries that make you exile them :P (dont know how often that happens, but still worth taking note of maybe)

There's bound to be some memory issues with Instants/Sorceries that got shuffled back in the library. Doesn't happen that often, but all it takes is for the same player to pack a single Day's Undoing to cause multiple problems over the course of 10 or so games. Unfortunately, in that scenario, not only can we not be sure if the card in question has been cast this game, but we can't even reference the card in question to make sure we're doing it right.

Maybe Uncommon Occurence is only supposed to be for funsies, though, and shouldn't be scrutinized like this? It kind of depends on your design philosophy. You could always spell out that it copies a card in the graveyard or exile. That should solve the corner case problem.

If you're trying to copy a targeted spell, this doesn't contain any provision for choosing new targets, so you have to stick with the same targets that the original spell had...which may not even be legal by now.

@jmgariepy: There will be no memory issues any worse than for any other spell interacting with the stack. This targets a spell, so an object on the stack that either got their by casting a card from somewhere or the copy of a card somewhere.

So as long as you can remember the spells on the stack this won't be worse.

Ah. I'm not sure if that's Froggychum's intent. Sure FC wrote 'target', but also wrote 'cast this game' which I assume wouldn't be necessary if the spell was still on the stack. Froggychum?

This card is a bit looser than a stack-based Fork, and I don't want it to only be playable right after the spell is cast / is still on the stack. It should not be limited to on-the-stack cards.

Whether you have cast the card and are Forking it, or you are copying something from your graveyard, even if you just want to play another spell that is neither in your graveyard or being resolved currently. this card should cover it :D

Also, has anybody any appreciation for the fact that I named the uncommon card Uncommon Occurence? deetails!

I think, unfortunately, this needs to be something like:

Cast a copy of target instant or sorcery card from your graveyard or that you have exiled.

And even then probably technically doesn't quite work without comprule changes.

Casting spells that exile themselves is dangerous. Lots of spells do that as a hedge against abusive multiple uses.

But I can see this as a variant wish; it's certianly a thing blue can do. I'd suggest upping the blueness of the cost - maybe all the way to . It's probably OK for a dedicated spell manipulation deck to do this sort of thine; it's less a good idea to be able to splash it into a black deck.

sure. I will edit its cost

sure. I will edit its cost

and the new text you suggested sound a lot worse to me, just doesnt flow. I suppose that's okay, but it also doesn't fix any problems, and makes it less general and usable

Is it just me or is this card insane? A little harder to pay than Snapcaster Mage, but you essentially get a non-exiling Flashback effect for ANY cost card in the GY for only 3. Snapcaster happens with equivalent timing, but you still gotta pay the cost of the spell you're re-casting.
