Use Prophetic Flamespeaker with things like Xenagos, God of Revels, Ghor-Clan Rampager, and Varolz, the Scar-Striped to trample over blockers for massive amounts of damage from double strike, and possibly a Dictate of the Twin Gods.
Prophetic Flamespeaker: The main goal of the deck is to pump this guy up and get him to have extremely high power for the double strike and trample win. He also gets card advantage.
Courser of Kruphix: Gets me some land and lifegain when I need it.
Ghor-Clan Rampager and Pyrewild Shaman: Work best when I bloodrush them onto the flamespeaker, can also work fine as creatures.
Scavenging Ooze: When my own or my opponents creatures die I can get some value off it with the ooze. Works well against graveyard decks especially.
Varolz, the Scar-Striped: When i have excess creatures in my graveyard i can use them to get counters onto my other creatures.
Xenagos, God of Revels: Can be a huge pumpup for my flamespeaker if i scavenge some things onto it before combat.
Dreadbore, Hero's Downfall, and Mizzium Mortars: My removal package specializes in taking out planeswalkers and creatures. Enchantment removal is in sideboard.
Whip of Erebos: Reanimates my creatures and gains me a lot of life.
Dictate of the Twin Gods: Doubles my damage at instant speed, useful as a one of because once in a while it can win you the game.
Domri Rade: Card advantage and removal.
