But how do you make sure your plan succeeds? Breeding HA gives a somewhat 40-50% chance to get your normal ability.I'm breeding a bunch of HA good IV female Ferroseeds and going to WT them (60% of them will be HA, but I won't bother to check because you need to evolve it to find out). Then I'll watch the world burn as people evolve those Ferroseeds and find an Anticipate Ferrothorn, or unknowingly use them as parents and WT HA spitbacks away to repeat the cycle.
Better to clone successful Ferros and spread the devilish seed for sure!
Hope I could help to make the world a bit more into hell.
