Question

What are all the items to help breeding?

Comments

What do you mean by that exactly? Like, are you asking for items that'll give you a baby pokemon instead of a regular one? Example: item that'll give you Munchlax from an egg instead of Snorlax. <––Is that what you're asking for?
Sorry, I'm a little confused about the question. That's all

Answer 1

Incenses for getting some Baby Pokemon

• Sea for Azurril
• Lax for Wynaut
• Rose for Budew
• Pure for Chingling
• Rock for Bonsly
• Odd for Mime.Jr
• Luck for Happiny
• Wave for Mantyke
• Full for Munchlax

  Everstone for passing down Natures

  Give Everstone to Parent and then chance of getting the same nature as the same parent will be 100% in black and white 2

  Power Items for passing down Iv's

  Each power item relates to a specific Iv. For example, when the male parent holds the power anklet, the baby will get the male parents Iv.

I could have missed some.

Also oval charm increases the egg you get, but not sure if thats what he want

Answer 2

The only item that is related to your question is the item, light ball, if I remember the name correctly. If you make a girl Pikachu hold it and place it in the day care with a male Cherrim, you should get a Pichu that knows Volt Tackle.

This what I know as far as you question goes. I recommend going to Pokemon.com/the game mechanics on the database, or wait for someone else to answer.
Other than that, I can't help you to the extent of your question. I hope this helps anyway.
