This deck is all about cast huge fiery X spells right at your opponent's face. In the early game the deck focuses on playing mana ramp like Mana Vault and mana doublers like Mana Flare and Gauntlet of Might. Then, with a mana doubler or two in play the deck can use Candelabra of Tawnos to produce even more mana and when the time is right put all that mana into one or two giant Firaballs.
Another strategy that can be used is bouncing the Candelabra and Mana Vaults with Hurkyl's Recall to "reset" them and produce more mana. Last but not least the Candelabra of Tawnos can also be used with Mishra's Factory, Maze of Ith and Library of Alexandria for some extra value.
You can build this deck without Candelabra of Tawnos and instead go all in on the mana doublers and Forks, then the deck sometimes is called Big Red.
