Design Guidelines for Racing+ Seeded Starts

|   Design Guidelines for Racing+ Seeded Starts  |
| (thanks to Chronometrics for formalizing this) |
+------------------------------------------------+

First, review the existing starts:
https://github.com/Zamiell/isaac-racing-client/blob/master/src/data/builds.js

Any additional starts should meet the following criteria:

1) The start should have a playstyle that is not found in any of the existing starts.

2) The start should have some sort of skill component.
   (e.g. No powerful abilities that are very easy to play, like the Afterbirth+ version of Isaac's Heart + Blood Rights.)

3) The start should be a multiplicative power increase that scales throughout the run.
   (e.g. No +4 damage.)

4) The start should not contain any items currently in another start.

5) The start should comparable in power level to the current range of starts.

6) The start should have a natural synergy.
   (e.g. Something + The Mind is not a synergy, it's just two good items.)

7) The start should be as elegant as possible:
    - The fewer items, the more elegant it is.
    - The cleaner the interaction, the more elegant it is.
    - The more the items seem designed for each other, the more elegant it is.

8) The start should not rely on RNG. Seeded races should not rely on RNG, even if it is marginal.
   (e.g. No Holy Light + 9 Luck start.)
