But if he stopped at the phantom stage, it would only cost him 5 million years of lifespan and an extra hundred or so. Even if he made two incomplete copies, he would only spend 10 million years of lifespan, leaving him with a profit of 3.1 million years.
This was one of the reasons why Loki decided to expose his ability to make copies of Supreme Metacs. With an income of 3.1 million years of lifespan, he could finally tackle some of the things he wanted to do without having to worry about the cost of lifespan.
The other reason he was willing to display his extraordinary talents was so that he could copy Supreme Metacs into the spark of power. This one was even more important than the lifespan he would gain. In particular, it provided him with some raw materials for his next round of experiments.
