Gruul Champion (Standard)

The main goal of this deck is to cheat in large creatures using Champion of Rhonas.
Failing that, it has a decent energy package to help keep you alive to cast them normally.

The ideal draw and turn sequence would be:
Turn 1: Bloodlust Inciter
Turn 2: Servant of the Conduit
Turn 3: Champion of Rhonas into one of the big drops

Big drops:
Sifter Wurm is a way to gain some life against aggro decks and hopefully sort out your next draw.
Aetherwind Basker can generate a lot of energy and can sometimes just win the game when it gets the chance to attack.

Support cards:
Attune with Aether creates energy and smooths out your mana.
Bloodlust Inciter is mainly there to give Champion of Rhonas haste so he can bring something out the turn he comes down. But also works well with Voltaic Brawler for attacking turn 2 with a 4/3 or late game for giving your big guys haste.
Voltaic Brawler is there to put on early pressure and to eat up removal before the Champion of Rhonas comes down.
Servant of the Conduit is for mana to ramp into an early Champion of Rhonas or help wih the big drops.
Blossoming Defense is there to keep your stuff alive.
Spontaneous Artist is another source of haste, more expensive than Bloodlust Inciter but more flexible.

Removal:
Harnessed Lightning is just a great removal card for energy decks.
Magma Spray is mainly in due to it's low cost but the exile can also be relevant.
