Do you think this change would seriously buff earthquake?
It wouldn't increase your CC, because there are so few
/
decks out there, so it is unlikely that you could combo this with congeal or a squid to insta-kill creatures.
Furthermore, whatever synergy with
it creates is also limited by the fact that this could limit the efficacy of your freezes, by allowing opponent creatures to break free early.
Mostly, this would allow
to break free from ice, in exchange for a chance of shattering their creatures. Seems like something an earth elemental would do.
If this is a buff, it would be a small one. I think it adds depth, fits thematically, adds connections between
/
(of which there are too few), and helps weaken freezing slightly (which I think it needs)
