Despite being one of a series of "-1 agenda point" cards that aim to supplement Sportsmetal: Go Big or Go Home, Meridian isn't a particularly effective piece of ICE. The potential tempo swing is such that a Runner will nearly always opt-in to the -1 point at least once, and the single subroutine is easily broken with any number of Runner tools once they have their board set up. In this way it ends up being something of a gimmicky binary ice with a Runner's-choice bypass, albeit a relatively costly one for them.
However... where Meridian shines is with Sportsmetal's suite of "Runner's score area" cards. Alas, Game Changer is no more, and I'll miss Project Vacheron just as much as Domestic Sleepers; but Meridian is most useful when it's fueling a Fast Break or preventing access on the Giordano Memorial Field. Out of faction there's always a good ol' Stock Buy-Back
As ICE itself it needs something more by way of support in order to be worthwhile. Maybe a Rover Algorithm or perhaps even a Rime to boost strength?
