The material cost for Black Holes and their upgrades will be reduced by 2%. In addition, each black hole up to the number of completed BHCs will give 5% chance of GP per hour. These both cap after 40 BHCs, for 80% reduced material cost and GP generation tripled for a maximum of 3GP/hour (1 GP from the first 4 black holes, as usual, plus 2 GP from 36 black holes).

GP per hour from black holes will be

0.25 * [Number of BHs (up to 4)] + 0.05 * [Number of BHs (up to the number of BHCs)]

The materials needed for a 1/1 BH will decrease after each BHC according to the following table:

Strategy
The first BHC will likely take 10-15 times the divinity needed for a UUC. With 100 CC you need about 13 quintillion (1.3E19) divinity for a 1/1 Black Hole.

10k% BS and 1m clones let you build a 100/100 divinity generator in a bit over a day and the BH an hour after that. More is better, as always. Anything that creates divinity faster (like pet campaigns) helps.

In the midgame mark, these should be relatively trivial for most players with an X/60/40 div gen and a 1 hour pet campaign.
