Because of Poppy's Zekrom set, mostly, the use of Mr. Lol's Kyogre set seems to be the best option. Both can easily dent Ferrothorn beyond repair, and make breaking past it, especially considering the huge recoil Poppy's set will likely take, much easier.
Firstly, I would not consider a Kyu form for this team. It already has an SR weak sweeper, and a large inability to switch into Dragon type attacks. The need for prediction on any of the mentioned sets also troubles me, as this team can really not afford to allow the opponent the chance to set up. Neither provide any of the type resistances Heavy offense like this will need to function, and both will provide many chances for the opponent to set up and possibly sweep.
Kyogre also adds a valuable Ice resistance as noted earlier. The inclusion of leftovers as the item means that this obviously offensive team will still have a little bit of bulk against special attacks, likely to set up after a sac, or KO. This Kyogre cannot easily be walled either, and because of the aforementioned Offensive nature of the team I believe a set with less chances of failed prediction, as compared to the Specs Kyogre set, will cause less turn of forced switches, and with the minimal bulk of this team, forced switches will often spell KOs. In other words, losing momentum on a misprediction versus, say, Latias, with the current team means that much of our team is in for a lot of pain, while mr. lol's set can at least render it easy to revenge through thunder, and maybe even beat it.
I also think that the loss of offense is not as significant as it may seem, especially considering the lessened prediction. We can still break ferro, and even chansey will be left broken and nigh useless after beating us with toxic, though it will accomplish this. Lastly, even though this set has more hard counters than the specs set, all of them are easily able to be set up upon by our other, physically based teammates, while the set still retains much offensive synergy by weakening problem pokemon like Ferrothorn and Latias, and also providing a way to force out troublesome physical walls like Lugia and Groudon, should they begin to entrench themselves.
