I agree that the card requires some work to fit into an environment. It
can be run in virtually any red-heavy deck, but it's stock goes
way up with an archetype surrounding it. I think one major problem is people try to put it into decks that want to speed the game up. It's 100% better in
long-game decks, which has been one challenge in developing the archetype properly. Vortex and
Seismic Assault act more fluidly as a sort of board control engine, which pivots into a wincon once the game is stabilized. Less-developed sections of the engine (say, only Vortex +
Crucible) have worked well solely in the board control role, with
other cards as the win con.
Stormbind may be an important piece I'm missing, but I'm hesitant thinking that the random discard will be too much of a turn-off for the group.
Again, definitely not for every format. But it's a very rewarding card for a rewarding archetype if you invest in it.
