Let me start:
Earth is also having a bad start (worse than us), but they do have a lot of cards hidden in vault. We can still expect a few surprises from them.
They have lost their denial grabbow twice though, and have not salvaged any good grabbow materials, so we can reduce the threat of that.
vs Entropy, they're scared of CP Wyrms or Wings, maybe both. If they have a Fire Duo with RoF/deflag saved for air, I expect it'll come here. Or else they might try Denial grabbow. For Life they need to maximize their rush, so parhaps Graboids or standard Mono. For darkness they're afraid of RT splash, which darkness can do effectively alone or with ghostmare. If they've saved fractal it might go here, since their immortal has been weakened. For Gravity their Zap Grabbow is extremely effective, can't think of anything stronger.
So the most likely candidate for us are Immortal (weakened) or Dark Domin. Pulvy Smash is still around as a potential go-to deck of course and Denial grabbow has a faint chance of showing its ugly head.
Spoiler for Time:
Time's matchup vs Air is a bit complicated, since air can effectively stall or rush, Time needs to mindgate whether to use Ghostal or ghostmare properly. Based on Jenk's analysis they have all other elements as better stall targets than time, so I'd say they'll bring Ghostmare here. Entropy has a problematic grabbow, so I'd expect Pharaohs or an RT deck of their own (Graboids perhaps?) Pharaohs seem like the strongest option, but it might suffer to disco which might make Time bring their own grabbow. Fire is tough for time, and I'd say RoL/Hope is one of the best decks they have as it beats everything but firestall decently (and almost all other elements for fire are good firestall targets). But Spike might have the fallacy of overestimating RoL/Hope's weakness and bring Pdials instead. Life as a whole is iffy, I'd expect an OTK deck here.
Which leaves a lot of options for them vs us, but I'm kinda sure that Pbow is coming. If I were writing this analysis as a spectator, I'd start with Pbow vs aether first as it seems really really strong. Other options such as Ghostmare, grabbow and standard pharaoh decks seem much more inferior in comparision.
