I agree that some consensus is good, but I think we also need to come up with some idea of what we'll DO with that data. Again, depending on the approach you're playing, these decks can end with wildly different results for you, and even the so called 'easy' decks can just clobber you if they get a good draw, or you get a crappy one.
Does anyone actually want to get chewed up and spit out completely regardless of what the opposition is? Do we need to make Miracle into a powerhouse that's as hard or harder than Hermes (who we all seem to agree is just completely brutal and punishing to an unreasonable extreme according to the pole)?
Does Ferrox (just from the most recent example) need an overwhelmingly powerful shield in addition to its rush-deck nature combined with benefits like double base HP, triple mark, double card drawing, and the ability to use more Feral bonds than a human player ever possibly could? I certainly don't think so.
You've probably only got a 50-60% chance against the current version of Ferrox using entropy rainbow, time rainbow is likely to get swarmed under, and RoL likely can't deal the damage to compensate for like 200 healing a turn or whatever Ferrox's insane max is.
Is it important that we make that deck more difficult because it doesn't beat you 9.5 out of 10 times like eternal phoenix?
What we REALLY need a pole on is this question:
"Is it a problem that we have less difficult (but still very capable of winning) FG decks in a random pile with the ones that leave you abused and bleeding from every orifice after each match?"
I would submit that the answer is no.
