Ack, not the Shroomish! My luck with breeding those is so bad... T.T
For the other 7...how about both the Dive and Heal Charmanders, Pumpkaboo-XL, Calm Dive Flabebe, and a simple EM breeding project (the Snover or Tympole in my Wants section)? I can provide a female parent so you can also breed for yourself (Dream Ball HA Snover / Net Ball HA Tympole). Lmk if this is okay, or if you want to make changes. Looking to expand your Sinnoh stock? :)
Do you want to do flawless or spitback? It'll take some time for me to breed everything fyi...
