Maybe someone can enlighten me... What is the chain breeding in order for the Blissey evolutions to learn Seismic Toss?
I'm facing a trainer online which has a Blissey with Seismic Toss, and last I checked, it could only have learned that from the move tutor in FireRed and LeafGreen. And since the Bank isn't out, there was no way of a transfer.

Mankey and Primeape probably still have Seismic Toss as a level-up move, so try asking around on the trade boards.
Then, try breeding a male Mankey/Primeape that knows Seismic Toss with a female Pikachu, Raichu, Clefairy, Clefable, Jigglypuff, Wigglytuff, Snubbull, Granbull, or Mawile. If that works, just breed the offspring (if male) with Chansey afterwards.
