I'm considering the background of this card. The Space Comment just seems so off, but I have a theory.
The only other monster wth 'Magic Swordsman is Neo, that good ol' 1700 atk spellcaster from the early days. So, what if the 'canon' lineage is that Neo grew in power until he decided that he could safely venture into space. Now a space traveler called neo? Rings a bell right? So he becomes elemental hero Neos and kicks some tail, then returns to earth as Trance.
Just a theory of course, but figured I'd share!
I think this card deserves a better rating, it's ridiculous how can people underestimates the flexibility of this card, being a 1 Tribute and 2,600 ATK its a gift. Among the spellcasters, which only a few have High Atk (Black Chaos, Dark Magician Fusions, etc) he is really worth the buy. Constructing a deck on spellcasters, plus negation of cards its a wise choice. Imo he deserves at 8.0 rating. Nice card if played correctly.
