If he could get any cooler....
Drop your creatures onto the field as fast as possible as you remove, burn, and kill whatever threatens you (mainly the guy sitting across from you.)
Rakdos Cackler - Always, always, ALWAYS unleash this beast at the start of the game! The early game damage he deals is one of a kind. On top of this. He can be easily paired with Fists of the Demigod to punish the opponent with intimidating first strike and wither abilities.
Vexing Devil - Basically a creature spell that deals four damage to the opponent as it enters and leaves the battlefield.
Diregraf Ghoul - One Drop. 2/2. Comes in tapped. That's pretty much it.
Spike Jester - Looks like a clown but deals easy and quick damage like a... cheeseburger.
Mogis's Marauder - Bestows* upon your creatures haste and intimidate for one turn which may be enough to finish the frightened opponent. (See what I did there? :D)
Ashenmoor Gouger - Completely Boss. Dump Fists of the Demigod on it and it whacks the opponent.
Olivia Voldaren - That Stormbreath Dragon you have there looks great. But it looks better on my side.
Ashenmoor Liege - Support that hurts if they try to remove it! and a guy riding on a horse.
Desecration Demon - 4 mana. 6/6 with flying. AND opponent may sac a creature to tap and pump Desecration Demon.
Rakdos, Lord of Riots Flying, Trample, a 6/6. In addition, you can cast Mogis, God of Slaughter, Olivia Voldaren, and Desecration Demon for 6 mana if opponent took 6 life! Very Very helpful.
Mogis, God of Slaughter - The most efficient way to clear the board and hurt the opponent without killing your own creatures is a god.
Tanks for reading and help will be welcomed! Deciding if I should add More 4 drops or not.
