The idea is to quickly throw big, flavorful elementals into play. Typically, this is down through Incandescent Soulstoke, who combos incredibly well with smokebraider. This makes for turn 4 Supreme Exemplar or Nova Chaser.
Also included are Brion Stoutarm and Fling, to do even more damage and maybe gain a little life.
There are some weird choices and inconsistencies in the deck, but like all of my decks, they're built to include flavor and sentiment. I could have 4x any given card and nice lands, but I'm a casual player with money better spent.
