Decks Containing Thought-Courier

Okay. So generally, I'm guessing you'll get the concept of the deck pretty quickly - draw a bunch of stuff until you get Niv-Mizzet, and then start blowing everything away with all your crazy drawing stuff. (Hint: get curiosity on Niv-Mizzet for an infinite combo.) Also, you're going to want to use mind over matter in combination with the library to make sure you don't deck yourself. And also, try to get pemmin's aura on arcanis, so that you can just pay 1 blue to draw three cards. I realize that this deck is bigger than most usually are, but that's okay, since you'll draw through it in no time flat.

Use Ornithopter or Welding Jar as cheap spells so you can counter them with Fold Into Aether. Use Trinket Mage to get them if you don't already have them in your hand, and use Fabricate to get the Darksteel Colossus if you don't already have him your hand. All in all, this is a pretty fast deck. You only need 4 mana to dominate!

This deck has a lot of flying and unblockable cards along with cards that let you look at the top x cards of your library and put them in any order. Jace Beleren also helps a lot.

the creatures are all just fodder for day of the dragons

Color protection based deck that frustrates opponents. Here's some combos: Mind bend[MB]-Karma, Change to their lands(quick killer). MB-Cir of Pro. White, Protection from w/e color they're using. Shifting Sky works w/ llawan, 8 1/2 tails, or C.O.P. white. 8 1/2 tails works to protect itself and worship or plat angel to secure game. Thought courier gets rid of excessive duplicate enchanchments while ghostly prison & wrath slow down the early attack. Slowly grind though their life w/ equip of the swords as its easy to slip through w/ all the protection. The deck also gives back life when needed w/ champion & sword of life/shad. The deck runs kind of slow at 1st but once things get in place it's nearly impossible to get rid of them with all the color and protection changes and numerous combos.
