What set are these cards from?

[Sylmin]

Well I've been starting to learn sets by they're logos since I organised all of my cards by dex order, but I came across a few which had coloured pokemon sillouettes in the bottom right corner instead of the set logo. For the cards I have it's either a plusle or a manaphy. I tried to research them on google and things but there were no decent results. :/
The ones with a plusle sillouette 'logo' are:
Charmeleon
Mareep
Spoink
Beldum
And the one with a manaphy is Buizel.

If you can help, that would be great! Thank you ^__^~

Hope that helps.

Ah! Thanks so much ^___^ (Are they rare? XD)

Nope. They aren't rare. They are very common. Many, many people bought the Trainer Kits. Plus. The only legal Trainer Kit is the Manaphy/Lucario one.

The other Trainer Kits aren't legal for modified play. :(.
