I like the idea.
If you, y'know, cut out the whole part about printing Geminis. It's a dead sub-type, and it should stay dead.
Far from it, Gemini Spark if obviously broken, they have a load of decent support like Supervise and Woodland Archer plus you can bring out a 2200 beater that gives them effects. In fact the only issue with Geminis is that they themselves are no good.
OT, this card is pretty hilarious if you can get it out but I'd rather run Vanity's Fiend/Ruler which is similar.
