So, NEXT Ice has never been bad. Maybe it's never been great. But it's never been bad.
4/2 agendas have never been great. Sometimes they've been okay. But they're competing for deck slots with 3/2s, and while many 3/2s have rotated out (ding dong the witch is dead) the Projects are still kicking. A 4/2 agenda, therefore, needs to offer some compensation if it's stolen (like Explode-a-palooza) or some benefit if you score it (like Corporate Sales Team).
NEXT Wave 2 gives you...a brain damage. One. If you have NEXT Ice rezzed. That part's easy, honestly.
Or, it would be, if NEXT Bronze hadn't rotated out. Seriously, the whole point of NEXT ice is to be cheap, abundant, and self-reinforcing, so losing the only 2-cost ice in the suite is a bit of a punch in the genitals.
The core problem here is that doing 1 point of brain damage, by itself, isn't going to win you the game. It makes any future flatline easier, but only NEXT Gold has that potential in the required ice mix you have to run for this card. You could pair it with other brain damaging (or pseudo-brain damage like Self-Destruct Chips) to choke the runner's hand down. But generally, brain damage isn't a win condition.
So, to make this card work, you have to run an ice suite that isn't very good, score an agenda that could've been a Project Vitruvius, in pursuit of a win condition that doesn't really exist.
All I have to say, is that the next NEXT ice had better be good if this is going to see play post-rotation.
