This can probably only be done in Pokemon Black and White 2, you will have to go to a move tutor, forgot which one, and teach it!
its a special attack i think
She likes to pretend its an egg like Chansey's and Blissey's.
Roselia and its evolve can learn spike and toxic spikes and onix,machop and any other rock type pokemon can learn stealth rock
In Pokémon Black and Pokémon White, Forretress is not capable of learning Stealth Rock through level up or through the use of TMs, HMs or Tutors. Stealth Rock is an Egg Move for Forretress so you would have to use a female Pineco or Forretress and place her in the Daycare and then you would have to use a male Pokémon such as Dwebble or Crustle that would know Stealth Rock and place him in the Daycare and the Daycare Man will give you an Egg that will result into it hatching into Pineco that knows Stealth Rock.
A good support Pokemon would have to be a Pokemon that will help your team. You can try Skarmory for physical walling and spikes/stealth rock support blissey for special walling or you could try an annoyer Pokemon that forces switch outs on other teams such as rotom with confuse ray will-o-wisp ect.
No. If you want a Metagross with Stealth Rock in X/Y you will have to transer one from a game where he can learn it. These games are the Gen IV (back when Stealth Rock was a TM), and B/W 2 (via Move Tutor). Alternatively you can try to find a player who has a Metagross with these conditions willing to trade with you.
Wish Blissey was given out as an event at the New York Pokemon Center. There is no other way for Blissey to learn Wish short of hacking it onto Blissey.
