@DJ: Saw your comments on the First Impressions thread about opening hands, by any chance was it this deck? Because that seems to be the driving force behind my loses more than anything. You already know about the swap of a mountain for a swamp due to Black mana flooding, but there were an atrocious amount of mulligans I had to do because my earliest play would be T3.
EDIT: Just to be clear on matchups, I think Simic Ramp is probably just not there yet so I can't claim my 17 wins against it mean much atm. Against the discard aggro shell thats running around atm, its 50/50 depending on those draws. Control hasn't had much of a showing, but an annoying Grixis Dynavolt thing kicked me pretty squarely in the junk due to 3 toughness being a focus of most removal atm. This is still a good aggro deck, but I'll be trying out the other Rakdos brews when I unlock the cards to see if its the best Rakdos has to offer.
Yeah it was this deck: I still won all but one of the games with this deck. It's definitely harder to play though, when you never get to 3 or 4 mana lol. There's nothing wrong with the mana base, odd that we both had bad luck with it right at the beginning: buts it's just a coincidence.
I was having the same issue with Zombies, which runs 25 lands
