Assuming you've already got a bunch of bioroid ice in your deck, the only downside to this card is that it doesn't do anything on it's own. This is really only a problem early game. You can think of this similarly to positional ice, except it's temporal ice - other ice needs to be rezzed first.
It's 2 stronger than Viktor 1.0 for the same price. If you are one of the few people still using that card, swap them for this now.
