Changes Made. Description will be updated when the deck has a taste of some more battles.
Extra Mana and ways to cheat Elementals- Brighthearth Banneret and Incandescent Soulstoke. Attach the awesome Lightning Greaves to keep Incandescent Soulstoke from being Lighting Bolt or even exiled. Smokebraider, the start of it all! Use it as soon as you can, because when a creature kill/counter decks realize it boosts up the playing of Elementals faster, they will kill it.
Tutor- Flamekin Harbinger, to find elementals such as Mulldrifter for draw or Shriekmaw for kill. For some more control search out for Flickerwisp or even for the use of the champion ability, as well as having a flyer to block flyers.
Recovery- Reveillark, also is a flyer. Sunflare Shaman, for a strike back from board wipes. Horde of Notions, I use to think Vivid lands sucked until I realized there work best in a tri-color or more in mana. He brings your creatures straight on the field, and has haste, vigilance and flying!
Champions- Nova Chaser, Supreme Exemplar, and Changeling Berserker Thats flying, haste, and a trample. All very vital to the working of the deck.One leaves the battle field through the cheating from Incandescent Soulstoke and the other champion fills in its place. Championing is something especially when Horde of Notions is on the field and ready to go.
Late/mid game- You have a bunch of land just sitting on the field and draw into/or tutor Liege of the Tangle. Cheat it out with Incandescent Soulstoke for instant action or bring it on the field with the amount of mana dorks hanging around, attaching Lightning Greaves to it. Now your lands do your bidding.
Sideboard-
2x Glaring Spotlight is here to deal with a all hexproof deck. Since my friend's meta game is to play Illusions or something, running 'these will solve the problem. I would take out Vigor and a champion to put this in. Plus, since hexproof in my meta leads to counters and kill spells, its a great source to end the game.
Hound of Griselbrand against infect.
If you are having trouble with a certain enchantment or creature (in need of some more control) replace 2x Flickerwisp with 2x AEthersnipe.
Playing against mono-black- take 2x Shriekmaw out for 2x fling or 2x AEthersnipe.
Burn or kick kill in life- Doomgape, Vigor, needs to stay to teach burn decks a lesson!
