I don't really like the idea of using a permanent heavy deck vs earth, because they keep using pulverizer against us. However, pretty much ALL of our decks rely pretty heavily on permanents, other than monolight, or maybe one of the crusader decks (since we can endow and then not really care if we lose the weapon, especially with multiple copies)
The deck that Artha built vs earth, however, I think might do very well against Life. They've got a water duo, and one other deck, depending on what they kept (I suspect firestall, but that isn't certain) and I think that golden dragons + dims counters both of those fairly well. I was thinking of using a version of the dimshield/sundial stall against life; any creature deck they field will basically automatically lose vs that, but the firestall could quite easily beat it. To handle firestall, we could add something like 1 dragon/1 fractal, and 1-2 of the reflective shields. If they did keep firestall, I think it would be hard for them to have also kept emerald shields (I was trying to count their cards from exposed decks).
The other problematic deck Earth has is the stoneskin/miracle stall. We'd need quite a bit of damage to outlast that, and other than fractal, we don't have it. I think that our best deck overall against Earth would be the siphonary. It's probably the least vulnerable to pulverizer (since we can steal it) and their auburn nymphs are mostly useless against it, whereas they almost single handedly defeat our other decks.
Against air I have absolutely no idea what to do. They have too many decks for us to predict properly, and we have few enough that they can probably predict us fairly well. Just about the only saving grace we have is that their wings sucks against us. That, however, means they probably won't use it, and we might be able to get away with a crusader deck against them, either the darkness one, or the air one. I'd recommend the air one; we can then endow any OEs that Air brings to great effect, we can still attack past wings if they actually bring it against us, and we've got some CC for them as well. Plus, if we use siphonary against earth, we miss out on some of the darkness cards like steal, and I think we really need steal to beat earth's pulverizer.
tl;dr
dimstall/sundial vs life
siphonary vs earth
air duo vs air
