General:

• mostly went for a lower curve and more proactive incentives where possible. Most games ended up rather grindy and aggressive decks didn't get through. Might also be player preference though
• some more grave hate
• no interest in to "blood matters" cards, but a few blood tokens generated at the side fit well with the madness theme.

Specific Choices

- Bloodtithe Harvester is actually a good aggressive and versatile card, as well as working well with early madness, but I prefer the madness payoffs

Other Notes:

- Black still has too many threes
- not sure about the amount of ramp in green. Does is fit here?
-White could use some more efficient flieres
