With those teams all having six matchups, it'll be really hard to figure out which decks they'll send where, but if you think you can do it, go ahead. I think it'll be better to look at the kinds of decks they can field and just do our best against each possibility.
Against Air, the pulvy will definitely help against the stall; smashing weapons and sancs will hurt bad, but I'm not sure if it will have enough damage to win in time if they've got a bunch of miracles, and if memory serves, they had several in both their stalls. I think the fractal charger will do well against their best options as well, though; I'll try to be around later tonight for playtesting. The pulvy deck seems like it would be really good against light as well, though. Pulvy could be put into a grabbow, but I think we only had 3 left, which isn't enough to split between two decks effectively. If we converted that gravity shield last round (at work so can't check) I think that between gravity shield should be used here; between that and pulvy we can do well versus their stalls and adrenastaves.
Against entropy, if I were them, I'd use upped amethyst dragons, which doesn't die to a single lightning, so I think fractal chargers might be a really risky play; they won't have to wait for OTK, and can just dump their dragons/PUs out and rush. I think disquake grabbow might be better here, though; it would really mess with pugons bad, as that needs a ton of quanta. If they turn out to have used a grabbow or something, we can use the 'sideboard' event card and remove less effective cards. We should definitely send the lieutenant against entropy, both for this reason, and because I think we need the ups more there, and because the ups benefit us more than they would in the other match.
Also remember that we can make a sort of sideboard with the event card; with the grabbow in particular, that will give us some valuable options.
More when I get home from work.
