agreed, pendulum doesn't sound right for what the card does (by looking at the image)
/me goes on Word --> pendulum --> synonyms --> (no suggestions) >_< DOH!
ummm... what about:
Alternator? (too chessy imo)
Clockwork Pillar (too long?)
Alternate Production (pretty cool
)
Quanta Switcher
Quanta Changer
Duo-Pillar
Mechanical Pillar (cool)
Quanta Manufacturer
some suggestions
