Either Lotus-Ancestral or Lotus-Desire is the best deck in that format, and it's not very interesting aside from arguing which of the two is more consistent against Forces.
Lotus-Ancestral or Lotus-Desire might be "unbeatable" on the play. I don't see that that's neccessarily the case, especially with Time Spiral bringing Gemstone Caverns into the format, meaning that Turn 0 Orim's Chant or Stifle is possible. The challenge, like with the restricteds in place, is how do you win on your own Turn 1 without losing on your opponent's Turn 1. So Lotus - Ancestral - Force seems pretty good, because you only need to resolve 1 Lotus to cast many Ancestrals, so you can have a ratio like Ancestral > Force > Lotus. Lotus - Desire seems like maybe it would have a tougher time against allFoW.dec, because you need to resolve 2 Lotuses in order to cast Desire. So winning on Turn 1 through 2 Forces means having 4+ Lotus in your hand. To get that consistently, you'd need probably something like 40 Lotus 20 Desire.
But the format with restricteds is certainly more interesting. Maybe running Therapy + Nether Spirit would be a good way to effectively up your number of Therapies.
Also, it's too bad that Commandeer doesn't let you take control of the Storm trigger.
And Force of Will totally beats Rocket Powered Turbo Slug.dec, because RPTS.dec can only put 7 Slugs into play, so any deck that can play 1 FoW can live to its own Turn 1, where it can probably win.
Yeah, I'm pretty sure Lotus-Ancestral-Force is a lock in that format. Gemstone Cavern-Chant is almost strictly worse than Force of Will, as it costs three cards rather than two.
RPTS.dec still does pretty well on the draw, as eight Slugs requires three Forces (or Force + Foil) to beat.
I'm most interested in developing the combo deck right now, as that will dictate the other points of the metagame polygon (triangle?). The combo deck will dictate how the control deck is built, which will dictate how aggro or prison is built. Right now, the combo deck has to try to beat a 50% Force of Will ratio with an AK draw engine. The FoW deck is pretty much able to counter one spell a turn for the first 7-8 turns when the AK engine takes complete control. In the combo match-up, Intuition -> Sphere of Resistance or Rule of Law could also cause you some problems. Basically, what is the most disruption a combo deck in this format can run and still win turn one consistently? (The combo deck doesn't have to win turn one against control, though.)
Do we take into account the lack of information in these games? If I'm a combo deck playing against a control deck, and my Cabal Therapy is Forced, I don't know whether I'm playing against FoW.dec or a combo deck with Forces. I have no way to know if I can afford to pass the turn. This could make it a lot harder for combo to beat control, as it would have to cast enough disruption on turn one to know it was going against control or a combo deck that's full on Forces, but low on gas, rather than spreading the disruption out over several turns to get best use out of its permanent mana sources.
