Most of the "OP" decks being posted for this would not be workable at all. That being said though, there are a couple of things that make me hesitant to throw my full support behind this:
-It's a HUGE game changer. Introducing these cards would alter gameplay mechanics so dramatically that most currently used decks would no longer be competitive. (This isn't necessarily a bad thing, but it is one we need to keep in mind when discussing the card)
-As someone (
I think EvaRia?Mormegil) said, I can't see NOT using at least one or two of these in every deck I play. I'm not sure if this is due to it being OP, or simply having a huge variety of uses.
-There are a couple of decks that I am concerned about:
1) Light flashes in rustler decks has come up several times. Basically the idea is you put light flash in a life deck that uses rustler, and you can turn
to
then back to
and double your quanta. I haven't found any really ridiculous decks with this yet, but I haven't tested exhaustively either. To be honest I actually kind of like this one, but I still want to make sure it's balanced.
2 & 3) I'm also really worried about aether flashes in RoL/hope or fractal devourers. Both of these decks produce huge amounts of a second element, which if you could channel into aether you could fractal much more often. Since these are both already really strong decks I'm not sure if this is a good thing.
4) The forth deck I'd be concerned about this in is the fire cremation rush- normally this deck just doesn't use the off-element quanta produced by cremation, so you could toss in fire flashes and basically get free quanta in an already fast deck. Might be possible to get into 2 or 3 turns to kill range.
-It puts even more emphasis on rush decks. This might make me unpopular, but as it stands now I think the game is too focused on speed decks. There are already decks out there that can fairly reliably kill by the 4th turn. This card
would allow for decks even faster than that. It's getting dangerously close to first turn kill decks. (which I don't think anyone wants)
Now a few points in defense of the card:
-A deck consisting of a few novas, these and dragons will very rarely get you a lethal dose of dragon on the field before you deck out.
-Any deck that uses more than one type of flash runs into problems. Namely that if you're using multiple types of flash usually you need to draw & play them in the right order. If played in the wrong order or at the wrong time you end up pulling quanta back out of a pool you need it in.
-Trying to get things out quickly with nova & flashes (or something similar) is much less reliable than it seems.
Consider this scenario: I just played a nova and now I'm playing an aether flash. For the first quanta in the cost there is only a 1 in 12 chance that it will pull from
. But on the second quanta of the cost, one of my quanta pools is now empty so the odds have gone to 1 in 11 (assuming I didn't lose
to the first). Similarly on the third the odds have become 1 in 10. And that's just to play one flash. If I play a second the odds are 1/9 + 1/8 + 1/7. Basically it becomes less likely to work the more quanta you're trying to get early on, especially using novas or cremations.
