As about 9001 people pointed out that this card doesn't fit Fire, I will most likely change its element. However, I would like to think about the element that would benefit the most from this card, rather than the element that fits the theme the best, and adapt the theme to it rather than the other way around. Theme is important, true, but card games are mainly maths and mechanics.
This is why I'd like to keep this card away from Life (which has Mitosis as an alternate creature production method) and Aether (which has Fractal and Twin Universe). Many of you suggested Light: may I ask you why you consider Light to be more fitting than Fire? To me, it's even less fitting, theme-wise, so I'd like to understand your point of view.
From a mechanical point of view, this card would be useful in about every element as long as it is a mono card. However, I think Aether, Air and Life would benefit less than other elements, while Light, Gravity, Entropy and Darkness do not fit.
A Death version is possible: a sort of necromancer or similar creature than brings forth an undead copy of the creature.
An Earth version is possible: the theme of construction fits nicely.
A Time version is possible: a creature that brings a copy of that creature from another time, possibly from the future.
A Water version is possible: water brings life, so the theme can be adapted.
