Mkay, the reason BH/Discord decks use Entropy pendulums is due to the goal of getting Discord out as early as possible. Without more Black Holes, this slowness in your deck will show even more. If you want Flying Weapons, I suggest going Air mark and pillars OR using Novas. Speeds the deck up on the whole.
You also barely have any offense, which makes the quanta denial a bit redundant. Unless you get that Amber out, you have no denial mid-game or late-game, and since the opponent will often have much quanta by that time, it's a prime target for CC.
In this case I use the entropy mark to get discord out even faster, and carry on with a second purple nymph without SoR to continue the killing. CC is normally a killer there, but I can usually draw out some CC with the Discords, as only one is really needed. After that, I can be "almost" safe. Higher problems here are Fire Shields, that kills the nymphs without even looking at them.
I avoid using Nova's because the SoR could draw out Air Quanta, and I lay there with a dead card in hand. It may be a good Idea, but it relies too much on RNG for me.
The air mark might be good, but then I'd have to use pillars of both elements, which would be kind of hard to balance (yet, still works.)
[short reply] : its a nice deck, but it takes a while to set up.
[long analysis]:
The main attacker is the discords.
Support is cumming from Blackholes/ nymphs.
Shards of readiness act to "improve" the standing of the nymphs.
...
This deck has some good strengths.
*Impressive quanta denial.
*"relatively cheap" quanta requirements.
*locks down the opponent mid-game, late game.
The longer this deck is in play, the more and more this will harm the opponent.
...
Problems (at a glance)
*Early rushes could overwhelm this deck if they have too many out.
*damage by nymphs is "directly" too weak, and you rely heavily on discord + addition of another card to do "direct damage" if your opponent can take down one nymph, your deck is done for.
*Shards of Readiness is a nice addition but useful for 3 out of 26 cards. Its a "last ditch" maneuver, and not really helping; by mid-late game you have all the quanta you need to continue your attacks.
...
Suggestions/recommendations.
*you need to somehow add some protection to the purple/amber nymphs.
*if other CC/ PC controls are in the hand of your opponent at any time, this deck doesn't have any "walk in counters",
*deck relying on "set up" needs a way to stall. add fog shields instead of SoR.
While the direct damage is slow, I rely on some small stalling before I set up to survive long enough. While the SoR's aren't needed late game, a Purple Nymph in my starting hand is played relatively earlier and can cause me a head-ache if I don't have the quanta to heal myself with it (in which case SoR is useful.) While I do end up having some excessive quanta late-game, the boost that SoR's give early-game is too big to ditch.
Early rushes are a problem - (specially Immo Rushes), but Mono Rushes (Like Shrieker Rush) can get killed easily by the Discord that comes rather early - while a few others take a turn or two too late to come up and around.
I'd add some protection to the nymphs, but the only way to do that would use Aether - Something that, thinking now, would be good because of the PU to have "More nymphs".
