There's actually tremendous upside to this new card. The fact that it costs 1 instead of 3 is huge. Normally, you'd max out at two seismics whereas there's no real drawback to running four of these. You can play it early through pierce/other soft counters and having spares nets you more redundancy against abrupt decay or force of will--usually the only hard answers most decks have to these enchantments. it pairs way better with bob, especially against tempo decks. On the flipside, it is much worse at killing people than seismic but its still a much faster clock than punishing fire.
