The idea is to churn out huge creatures early by using the mana acceleration spells. The deck starts to fizzle once it's spent its hand; Rite of Flame > Desperate Ritual > Seething Song > 5CMC creature will dump 4 cards right off the bat, so I will most likely throw in 4 Browbeats to help deal with hand replenishment. Pyroclasms may also be worthwhile to wipe out chump blockers. 2x Furnace of Rath may be worthwhile to seal a game once they hit 10 life. Blocker removal may also be worthwhile to ensure that the creatures actually swing through unimpeded.
