I have both, i don't need Scraggy/Scrafty anymore and in the ruins from that cave in the desert in one part of it it has 5% chance of finding sigilyph.
i can get ya Slowpoke, Natu, Nincada, Seviper, Shuppet, Phantump and Yungoos. (if ya have access to Kabuto, Aerodactyl, Tirtouga and Archen i would be even more happy to trade with ya, if ya don't its okay and then send anything.)
I can get ya one, can you breed a Happiny in exchange, if ya don't have it i'm looking for Shieldon or Cranidos. (Forget the Happiny, i have one in the pc due to being blind i didn't saw it :v)
