Fragmentation of data looks flawless once again and, while I appreciate you're trying to put in as many cards as possible, we'll have to streamline that because it'll have to be the same for all of the players. In the whiletime, if you do tests like this and think that one of the extra cards you're recording should be officially recorded, just ask in here and I'll be sure to answer you.
Reduced the amount of needless data. And so:
1, Some sort of reusable CC-s are counted (Otyurg, Arctic squid) and others are not (Maxwell, Mind flayer (only counted, when there was enough quanta to use ability multiple times), Owl's eye).
2, EQ vs Poseidon (same with Mind flayer) and Steal vs. Deflagration.
3, SoGrad vs Empathic bond.
4, And mass CC's.
vs means one of them is counted, while the other is not and I don't know why.
From 1-4 which is important enough to be taken in the database and which could been deleted? (I don't delete until I know I should).
We'll have to start stating that the recorded cards are getting recorded for a special reason, and not just because they have a kind of skill. We'll see this in a moment:
1.Otyugh can possibly indicate Swallow, if anything I'd be prone to removing this and simply record this via "Creature Control". Arctic Squid isn't really CC, although it's accounted as such, and it can mostly be solved via Epinephrine. We'll want players to know that they can solve this kind of problems with Epinephrine or that they can play Catatitans and hope in a freeze or stuff on it. I'm still undecided on Maxwell, generally, decks who fail against Maxwell are the same who fail against other CC, this means it isn't relevant which CC killed it. As for Mind Flayer, thanks for making me notice, that's another thing to add. You should notice I put Lobotomizer in Aether, this means I'd want to know whether my cards are lobotomized or not.
2.Poseidon isn't generally used, in the arena, dexterity+EQ is generally just fine. If anything, I may ask to add 1 to EQ whenever your opponent has an usable Poseidon, but I wouldn't want to add another card.
3.Empathic Bond is generally included in Healing, being realistic, no one will play RoF to kill a field of creatures who power opponent's Empathic Bond. SoG, on the other side, is a standalone card, meaning that you could even just spam it here and there. Also, while Empathic Bonds generally indicate a Life deck or something with fractals or mitosis, SoGs generally indicate a stall, that's why knowing that is here and now needed. If anything, I'd remove it, but some little more data cannot hurt.
4.Don't think I got this point. I have a AoE in Deck's Traits, but you had to add RoF and Plague (still forgetting Thunderstorm, by the way), IMHO, needlessly.
@Atom, I don't know about Fractal and SoBr. If it were you, knowing that the current meta has a lot of fractals and a lot of SoBras, what would you do? I don't think anything can be done, if not defending against pestal (which is already covered in Denial) or against Rushes (which is already covered in, guess what, rushes). As for GotP and Poison, that's it, they're covered in the traits, meaning you won't need to cover them once again.
As for the growth, that's generally a stall-breaker. Stalls usually focus on waiting long enough till your opponent decks out. If you wait that much, a growth deck will just out-damage your healing. All of the growth creatures, aside from Fire Spirit, can completely defend against Fire Shield, which is one of Stall's best friends. Also, SoPas generally indicate a Stall-Breaker, too.
