Notes on changes from playtest:

Green needed some work. I've added some 2-3 drop threats to make midrange a more attractive option against the aggro decks. This also allows golgari to stabilize and grind down the opponent.
Additionally I've added colossal growth as a redundancy for trample tricks. (I'd like to fit in more combat tricks like this in the future)
Streetwise is a great way to pump a creature late game or comes down as a 3/3 for 2
Noose Constrictor signals golgari reanimate
Thrashing Brontodon is a beefier Rec Sage which should stabilize some boards against aggro.
Hound Tamer gives a reproducible effect for adding counters. This may be too broken.
Shadowbeast is effectively the same as Voracious Typhoon but cannot be targeted for reanimation

Fast and Furious has difficulty importing into arena. I will make a note of this for future drafts. I haven't found a good replacement for this slot yet.

Sylt made a good observation that Oni-Cult Anvil needed an artifact to get rolling. I've added Stormclaw Rager as an alternate sacrifice enabler that provides needed card draw for the sackdos decks.

Boros has all of the creatures it needs to get through. What it needs now (in addition to the tiny anthems/charges) is a powerful team pump. Heroic charge fits the bill.

Professor of Symbology's role was as a discard outlet as well as an "ok" two drop. We already have Seasoned Hallowblade and Raffine's Informant(a better version of this card) for reanimator discard enablers. Sunhome Stalward will work better as an aggressive two drop attacker that also wears counters well wink wink.

Blue gets better early interaction and improved late spells/card draw.

Red changes are minimal in terms of archetypal changes but replace cards with better alternatives.
Apple swapped with bloody betrayal as to signal that stealing should be something red is doing (even though apple is the best steal)
