"Egg produces a number of nonviable biological “eggs,” equal to the number of mutants the Five have to resurrect.
The eggs are then injected with mutant DNA from Mister Sinister’s genetic catalogue, and then made viable thanks to Proteus’ reality-altering powers.
Elixir biologically gives the eggs life starting a new cellular replication process and husk growth
Tempus uses her time manipulation powers to quickly age the mutant husks.
Hope Summers uses her powers to enhance everyone else’s abilities. Hope’s powers allow the Five to operate at both their peak and in unison.
A telepath then copies over the mutant’s consciousness, recorded by Cerebro, from a copy made at the time of their deaths, onto the husk.
Through this process, the Five are effectively able to make new clones of deceased mutants, restoring their bodies, their powers, and their minds as they were at the time of their deaths."
The last run of X-Men before the current run, they discovered 5 mutants working together enabled immortality through resurrection protocols.

If the mutants would just wear black turtle necks and pitch this around Silicon Valley, they would be billionaires instantly.
