Option B it is then
Each time Immortality or Quint is used it costs 2,3,4
|1,3,3
(Anubis,Nymph,Quint)
This creates a creature valued at 6
|7
Therefore this should cost such that after the average number of uses (A) the total quanta cost (Q) is equal between the two methods.
Anubis is probably the source of the immortality so lets use Activation Cost 2
|1
The casting cost needs to compensate for the lower cost to create the Immortal|Elite Immortal.
Try this V?
Casting Cost: 6|6
Absorb Cost: 2|2
Pseudo Activation Cost: 2|1
Possibly Absorb cost 1?
