I already love this deck because it uses Sword of Fire and Ice :D. Snakeform amd/or Psionic Blast, perhaps. This looks like a killer deck, I wouldn't change much about it.
The Dragonauts deck is cool, U/R is my favorite color combo. I'd take the lava spikes out and replace it with a win condition like Dominus of Fealty or Call the Skybreaker.
W/R also needs a win condition... There's alot you can do with this color combo instead of 1-drops and 2-drops that prevent them from blocking (Firemane Angel comes to mind).
The mana bases for both decks look really tricked out must have cost alot! Just suggestions, not trying to be critical or anything.
-2knight of new alara
-2 gwafa hazid
-2 meddling mage
-2 talon trooper
-2 slippery bogle
-2 captured sunlight
-2 favor of the overbeing
-4 sigil of the nayan gods
+2 behemoth sledge
+4 O. Ring
+2 Jhessian Infiltrator
Other cards that would work well here:mulldrifter ,Masked Admirers or Kitchen Finks synergize with Nulltread and are good creatures. Bant Charm is good removal/protection. I don't know what other cards you have, so this is all i can think of for now. Hope it was helpful.
All four are great sets...
I would get 1 ARB and one TS, but that's only because i drafted Shards 2 or 3 dozen times and have playsets of everything i want from that set. If you don't have a lot of the cool cards from Shards, get Shards instead of ARB. Also: take a look at Conflux. Not quite as good as shards or ARB imo, but worth a look nonetheless.
I wouldn't play terramorphic expanse in conjuction with jungle shrine and elfhame palace; any more than 4 or 5 cipt lands will make your deck really slow. When you get around to it, try to go 4 Jungle shrine, no elfhame and 1 or 2 expanses tops. Aside from the mana base this seems like a nice casual deck.
My best friend plays a mean Dredge in casual. He uses Life from the Loam and Putrid Leech for a 2nd turn timewalker I've never played Dredge myself, so this suggestion might seem stupid: Fa'adiyah Seer. I think it triggers Dredge when you tap it, and at least it gets stuff into your graveyard. Also, Troll Asceticis my favorite green creature; he should be in every green deck
I bought a pack of Timespiral the other day with an Ixidron in it, which inspired me to build a fun multiplayer morph deck. Here's what i came up with:
Snakeform amd/or Psionic Blast, perhaps. This looks like a killer deck, I wouldn't change much about it.

The only suggestions i could make is rune Snag , Condemn, Path to Exile , and Oblivion Ring. Also: Loxodon Warhammer or No-Dachi > Ronin warclub.

I feel like it could be better, but I'm not sure of what to do with it. Tell me what you think.
edit: my friend plays a deck like this. For 1-drops you could also use Jackal Pups or Tattermunge Maniac.
