General Overview: Meant for multiplayer so its a little larger than normal Except, this one is meant to piss everyone off. 'Nuff said. Onto the card-by-card.
Card by Card
Creatures
Spiritmonger: These, along with your Phantom Nishobas are your premier fat beatsticks.
Shadowmage Infiltrator: Slips through most defense for a point, and keeps your cards coming.
Jungle Barrier: The only gold wall in existence, and basically the lone concession to pure defense this deck has.
Anurid Brushopper: Dodges anything that tries to kill it, if you have the cards to spare. Good all around defensive/offensive beast.
Meddling Mage: Identify and shut down combos, or just eliminate annoying/commonly played multiplayer cards.
Spells
Vindicate: All around kill card, to destroy whatever irks you.
Decimate: Similar role as Vindicate, though potentially more evil.
Backlash: Big fatty on the table? Make them feel the pain instead.
Lobotomy: Strip opponents hands and decks (and 'yards) of annoying cards.
Misfortune: I've seen this played but once, and it was insanely aggravating, hence it makes the cut easily 
Reflect Damage: What could be more annoying than going off with your 364 point fireball, only to have it come back and kill yourself instead?
Hero's Reunion: Okay, so another concession for defense. When they start gunning for you, just gain 7.
Fiery Justice: Potentially the only "diplomacy" card in the deck, but its really such a good multiplayer card that I can't *not* play it.
Hymn of Rebirth: Steal your opponents dead fatty and beat the snot out of him with it.
Pernicious Deed: Does this *need* any explanation? Wipe those pesky saprolings out, generally mass-kill whatever is annoying you.
Armadillo Cloak: Slap it on a Shadowmage for faster beats, or on a Spiritmonger for true sickness.
