Well, I will be playing Solidarity at the Grand Prix in Lille (France) and I did some extensive testing with the deck.

(Subject the First) 4 Twincast is a little too much.
I agree with you. Twincast is an extremely amazing card, but it is only good if you have other good cards in hand. Having multiple Twincasts in hand can be a problem if you're missing other relevant combo pieces.

I've discovered that Thirst is less than stellar and is good in less situations than it is decent.
Right, I've discovered the same... I've never been a huge fan of Thirst for Knowledge and I don't think it should be in the deck.

I decided that the meditate should go into the main and the 8 blast plan should be instituted for the board.
Actually, I can't see a reason to change that. I'm running 4 Meditates in the main and it has never been a problem. I don't think you need one in the board. I have been trying to fit one Peer through Depths in the sideboard, which has been nice (you can wish for it on turn three, or during the combo if you need it, etc.) but I don't think it's necessary. I just like to be able to wish for some draw and since Solidarity is not as popular in Germany as it is here, Sirocco doesn't seem to be such an issue . I'm running seven Blasts in the board, which has been enough for me.

(Mysterious Subject the Third) Let me just state something right now. NEVER, EVER, EVER, cut Flash of Insight from this deck.
Yeah, I tried it and it has been pretty nice. I think 2 is the right number for the deck.

(Also Mysterious Subject the Fourth) etc.
Unfortunately, I have not been able to playtest against this new combo deck, yet... But if it proves to be viable, there have to be some changes to the sideboard, that's for sure.


(Exceedingly Mysterious Subject the Fifth) This subject addresses the issue of the possibility of cutting fetchlands from Solidarity.
Wow. That's a big one. I think fetchlands are very important to the deck. In my opinion, the deck might get seriously weaker without fetchlands, because Brainstorm wouldn't work anymore (or not that good, at least), and you would have a higher change to fizzle during the combo, because of the higher land count in the deck. Without Brainstorm, the deck would loose one of the best spells in the deck, and therefore loose consistency. There is no card that could reasonably replace Brainstorm.
I don't even think, that you might be able to consistently combo on turn four without fetchlands and Brainstorm. But this has to be tested, I can't say that for sure.
It is true, that cards like Suppression Field, Stifle and Pithing Needle can hurt Solidarity quite a lot, but I don't know if taking out fetchlands would be the right way to handle the problem.




Oh, and btw., congratulations on T8ing in that SCG tournament. :)
