The opportunity cost seems very high. I pay $5 to buy it, then later when I play it, hopefully I have a $5 card in hand that I don't mind trashing. The ions are gained to hand, that's nice, but after playing them I still only have a 5-card hand. It's kind of like a cantrip that turns an expensive card in your deck into two labs. That doesn't sound so bad, except that I need to have that expensive card in my hand at the time I play it, what are the odds of that, and maybe I would want to be playing that card anyway.
It's hard to say, but I think this would be weak. It might also be interesting if the ions cost $5*, then they are one of the things that I can trash to get ions.
