implosion/xdude, since you guys will be testing decks heavily today, here are my thoughts for everyone's decks. Hope you guys can find decks for everyone.
Hobnob- Add another Miracle if we can afford it. Otherwise add another Light Pillar. Right now he has an illegal deck (15 light cards + 16 Air cards).
Helios- Playing against Darkness with few pillars (27 Pillars and about 6 Devourers after round 2 by my estimates). They have lots of cheap Darkness creatures still (Parasites and Minor Vampires) plus a few Dragons. There's a good chance we'll probably just see Nightfall'd Devourers and Minor Vampires plus some Steals, DL, and Dusk Mantle. But they could still make a Fractal Devourer deck against us. If they do, I'm not sure there's much we can do. I'd guess that our Earth-Light deck would have the best chance since we could get rid of all their Aether Pillars and slow down their ability to play Fractals. So here are my deck ideas (I haven't tested them though. They could be awful!)
5l8 5l8 5l8 5l8 5l8 5l8 5l8 5l8 5l8 5lh 5lh 5lh 5lh 5lh 5li 5li 5li 5oc 5oc 5oc 5oc 5oc 5oi 5oi 5oi 5oi 5on 5on 5on 5on 5on 5on
This against a simple Darkness deck. Focus Shockwaves on Devourers if he's low on pillars. Otherwise on Vampires (especially if they go with Adrenaline'd vamps). I used extra Wind Pillars + Air Mark to overcome Devourers knack of just sucking away the 1 kind of quantum we need. I think to make this deck we'd need to salvage Wind Pillars and Shockwaves.

I think this deck would have the best chance against Fractal'd Devourers. EQ their Aether Pillars. Hopefully we'll have more Titanium Shields then they have Steals. And then 2 Reflective Shields to switch to near the end before they try to DL us. You'd have to keep track of a lot though with this deck. Keep track of maximum damage if they stole your shield. Keep track of Darkness quantum and how much damage they could do with the DLs in their hand + if they drew another one.
This deck would do pretty good against a simple darkness deck as well I'd think. If you want more power, feel free to take out 3 Light Pillars and add 2 Dragons and another MS. But with Parasites, DL, and Dusk Mantle, I'm not sure you could kill them with this deck.
candle- I think that immolation deck could work. Even if they went completely Aggro, they'd still need to splash Fire just in case of Phase Shields. That means they can't use Graboids which means they can't play their fastest deck. Someone should test that deck though against an Earth deck with lots of EQs. I think we may need to change a Blessing or two to Light Pillars. But I don't know without some more testing.
xdude/implosion- I still think one of you should go with that Water-Light deck (but maybe a ~40 card version with 6 Ice Lances and 4 Ice Shields since they have Steals). I think implo should use it since xdude has more options available to him. What if xdude went with an upped Peggy deck w/ Momentum? Do you think it'd be fast enough to rush death? Hmm . . . you'd have to use Wind Pillars because the mark would need to be Gravity. But then you could use Fog Shields and Shockwaves as well maybe.

Maybe something like this? You definitely need to test it! I just threw it together in like half a minute. But maybe it'd be fast enough to rush Death. You could also go with Blessings instead of Shockwaves if you want more speed.
dragoon- I have no clue what to use for me. i've tried every possible thing i could think but the combination of discord, PC/CC, and creature spam is too much for me to handle. if you guys could find something that'd be awesome because I'm drawing a blank. Maybe if the decks above work, you can spend more time making my deck.

Btw, I tested a Hope deck with implo yesterday. But don't give me that deck! We can't afford to lose that deck. We need it against Earth in the future.
