Casual Immolating Souleater Deck. This deck is based around Immolating Souleater, Moltensteel Dragon, Assault Strobe, and Fling. By turn three or four if you aren't swinging for 20 you have already lost the game.
TIPS:
Turn 1 any 1 drop. Turn 2 Immolating Souleater. Turn 3 Assault Strobe, Swing.
There are a lot of combos that allow you to bounce back from an imperfect hand. Apostle's Blessing, protection allows you protection from burn, creature removal and to bypass all their creatures (including artifacts if you need). Moltensteel dragon can be played turn 2 with an infernal plunge and 4 life. Fling can be used as an alternative to Assault Strobe. Goblin Tunneler can make a souleater unblockable, then you pump it after it has been made unblockable, double strike it swing for 20.
Obviously since you invest your life in your turn 3 game ending swing it is important to keep yourself out of burn range whenever possible is crucial.
I occasionally sideboard Chancellor of the Tangles. Less reliable most of the time but very satisfying when you beat someone turn 2 after they used their first turn to Gitaxian Probe you.
Last thing left to discuss is Shocks and Galvanic Blasts can be used to bypass creatures also.
