All right, here are my cards. I looked through green and black and found some holes for aggressive decks to fill. That last half of the sentence...

Phyrexian Negator
Cao Cao, Lord of Wei
Champion of Stray Souls
Kalitas, Traitor of Ghet
Razaketh, the Foulblooded

Deathmist Raptor
Boon Satyr
Nullhide Ferox
Vizier of the Menagerie
Jugan, the Rising Star

The quality of white's creatures was pretty low, so:
Giant Killer
Precinct Captain
Seeker of the Way
Restoration Angel
Monastery Mentor
Angel of Invention
Realm-Cloaked Giant
Academy Rector
Eternal Dragon
Angel of Serenity

Thopter aggro
Goblin Sharpshooter
Thopter Engineer
Purphoros, God of the Forge
Pia and Kiran Nalaar
Hellrider
Flametongue Kavu
Zealous Conscripts
Glorybringer
Thundermaw Hellkite
Hellkite Tyrant

For my 8 white "creatures", I'm building on an existing enchantment/equipment theme with:
Dawn Evangel
Ghostblade Eidolon
Archon of Sun's Grace
Heliod, God of the Sun
Celestial Archon
Archon of Falling Stars
Ancestral Blade
Spirit Mirror
Two of these are not technically creatures, but they make creatures.

For red, I will build on a minor discard theme with two madness creatures:
Stromkirk Occultist
Reckless Wurm

FISH = Cursecatcher
FANCY = Falkenrath Aristocrat
DUNE = Desert's Hold
DIZZY = Ardenvale Tactician/Dizzying Swoop
BUDDY = Benevolent Bodyguard

Radio: Transcantation
Hope: Light of Hope
Rocket: Luminous Broodmoth
Chef: Hot Soup
Float: Galepowder Mage

Blade - Blade Splicer
Disgusting - Necrotic Ooze
Storm - Crow Storm
RIP - Rest in Peace
Shoes - Kitesail Freebooter

bulky - Irencrag Pyromancer - hard to get a bigger butt without a defender
throw - throwing knife - I really wanted to do chaos orb, because that's would make Dennis's brow furl. I knew he'd really really try to figure out how to implement that remotely. Then I remembered Slaying Mantis. But, this throwing knife is always interesting. Although, I remembered it not being that expensive, mana wise, compared to an axe... I guess it's a magical throwing knife...
outpost - outpost siege - always loved this guy, although it's a nonbo with the pyromancer. She longs to breathe free, not hide behind walls. She's no defender. {Achievement: attack with 3 0-power creatures. I'll save the prize on a new sheet.}
sleep - sigil of sleep - geez, I knew there would be good sleep cards on gatherer, but I wanted to add like 80% of them! This one can be the brutalest. Also, one of my brother's favorite cards. Not attack damage!
music - musician - among the really old mtg artists, I've always really liked Drew Tucker.
