Have you ever PU'ed a mutant? and then PUed the next copy? Look at its stats.
This card doesn't only rely on Mind Flayer and Lobotomizer .
I've had my share of experiencing Parallel Universe on a mutant (remembers the few times Gemini bested him with a mutant with momentum on his side of the field... -_- )
I know it doesn't 'rely' on those two cards, but the Brain Swap effect certainly implies that it works better with a Lobotomizer (especially since TU/PU are somewhat expensive in nature, compared to the Electrocuter).
