>>15360539If you absolutely cannot access more IV Dittos, you:
Breed until you get a Helioptile with Speed/HP.
Replace other Helioptile parent with HP/Speed Helioptile.
Breed until you RNG another perfect stat along with HP/Speed (or opposite gender with a new IV, with or without HP/Speed).
Replace parent (ideally replace Ditto for faster eggs) with new IV parent.
Breed until you RNG another new stat onto your HP/Speed one, and replace parent.
Repeat ad nauseum until you get the IVs you're willing to settle on.
