706.9e Until
Spark Double, there was no way to get a benefit out of having a
Clone copy another
Clone (which is itself not copying anything) over and over and over. If it gained an ability from doing so (like
Progenitor Mimic), it overwrote that eac The Mimeoplasm + h time.
Altered Ego was close, but the X doesn't track through cloning. But
Spark Double would add a counter each time, and that was just silly. It's not that it's too powerful—it's just weird that it doesn't work like every other "
Clone the
Clone to copy itself ad nauseam" interaction. This new rule changes that so it does: copying something else wipes out the other bonuses of the first copy effect.
