You can get all expired limited epic dragons by breeding the expired target dragon with another epic dragon. You can get expired limited hybrids dragons by making both parents the target dragon.

Since your son has neither of the rift dragons, breeding one would not be possible via Cooperative Breeding. The good news is that they will most likely be back in December for Bring 'Em Back!
