Are devils worth 7 blood each?

[Soapyfrog]

I'd rather be getting 30 devils a turn and paradropping THEM onto my opponents.

I think you could reasonably have 30 contracts by turn 50 AND have summoned most or even all of the unique devils if you play a blood nation like Abysia BoH or Mictlan.

That translates to 4-500 devils generated at a cost of less than 4 blood per (and dropping), at turn 50. You want your devils NOW? I want them now... and later... and later on... etc etc.
