Step 4 - Creating Super Studs

All Pokémon with two egg groups

What are Super Studs?

Super studs are male Pokémon who belong to two egg groups, and have five perfect IVs. Their superior genes pass down IVs swiftly, and their two egg groups allow them to breed with many Pokémon. They can also pass moves from one egg group to another.

Core Super Studs

To cover each of the 13 egg groups, you should breed super studs of the following species:

Clauncher (Water 1/ Water 3)

Magikarp (Dragon/Water 2)

Shroomish (Grass/Fairy)

Volbeat (Bug/Human-like)

Whismur (Field/Monster)
Woobat (Field/Flying)

Yamask (Mineral/Shapeless)

Using Friend Safari Dittos or other super studs, pass down five perfect IVs. Since nearly all Pokémon benefit from max HP, Defense, Special Defense and Speed, your super studs should also have perfect IVs in these stats. This mean the only non-perfect IV should be either Attack or Special Attack. 

Ideally, super studs sharing the same egg group should not have the same IVs; some should have non-perfect Attack, and the others Special Attack.

Additional Super Studs

To cover all connections between egg groups, you should catch:

Archen (Flying/Water 3)
Cacnea (Grass/Human-like)

Dwebble (Mineral/Bug)

Ferroseed (Grass/Mineral)

Horsea (Water 1/Dragon)

Lotad (Water 1/Grass)

Luvdisc (Water 1/Water 2)

Marill (Water 1/Fairy)

Paras (Grass/Bug)

Phantump (Grass/Shapeless)

Scraggy (Field/Dragon)

Seedot (Field/Grass)
Skitty (Field/Fairy)

Skorupi (Bug/Water 3)
Slowpoke (Water 1/Monster)

Snorunt (Mineral/Fairy)

Snover (Grass/Monster)
Spinda (Field/Human-like)

Stunfish (Water 1/Shapeless)

Surskit (Water 1/Bug)
