Here's another line of cards I thought up. Cards based on music. There aren't many at the moment, but I'll add more if and when I think of them.
The basis is that sound, which is how these monsters attack, is pressure waves, hence the WIND Attribute. Spellcaster-Type was the best I could think of for the Type. ("Musicman Synthescyther" is Machine-Type, because music synthesisers are machines. They support and modify music, which is what the monster does.)
I figure Spell Cards are the most effective representation of pure music, so they'll feature quite strongly in this series. Discarding Spell Cards, retrieving Spell Cards, that kind of thing. And quite a few "Musicman"-related Spell Cards too, why not?
I've just had a thought that "Musician King" would fit nicely in here, so let's throw him in. I'll see if I can get a card to Summon him (more easily than the required Fusion Summon, which uses a banned card - not impossible, but difficult).
If this theme appeals to you (it's looking more and more like a copy of my "Another Planet" series, which also contains 1 old Fusion Monster and a whole bunch of custom cards), then feel free to contribute.
