Okay, I think my previous post might have been a bit too hateful (probably your previous one as well), so I just want to calmly tackle the argumentation again.
It's probably to do with the sole fact that tones can't be transmitted perfectly in forums or whatever but in fact I think that we're in the same boat here.
First of all, I've been playing mana Dredge for years and even since I've heard of the manaless variant I've always been a strict advocate for the mana build. That being said, I'm not an extreme fanatic or something like that of Rausch's list (as it seems you supposed). Gigapede for example is a card that I find completely useless in manaless builds and his sb is far from optimal. Maybe I spoke a bit too positively about it, because I thought you had spoken too negatively about his deck.
What I have been doing however, despite knowing that mana Dredge is the way to go for me, is testing the manaless build a lot in order to find out where it fares better and worse than the traditional one. My main testing object was boarding plans against hate, for its inability to beat hate is actually the huge argument against manaless in my eyes.
The testing I referred to was against Team America, GBW Rock and UBG Dark Thresh, all of which had the 4 LotV in their sbs. The decks are definitely competitive and the players I tested with knew what they were doing. I don't claim that they're pros, but they know what they were doing.
So as I said we're actally on the same side. I only wanted to test the manaless build, especially the anti hate strategies, just like you. Only that I have finished it for now, coming to the conclusion that there is no viable strategy, while you're still at it. Also I'm not an advocate of Rausch's build, but at the same time I accredit his success. Just as much as I'm not an advocate of the manaless build in general, but I accredit its viability in the current metagame. And I only share expieriences, just like any other poster in this thread. Ajfirecracker just suggested a transformational board with the dark depths combo, I suggest not doing anything about it. Everyone does what he wants and just shares opinions. It's not like anyone came up with 7 Islands plus Vizzerdrix in the board. And that's fine in my eyes. I hope in yours too.
