Earth Attack

[incognito]

Getting clobbered with Earth Attacks. While it's probably too late this game, curious about the best defenses to this commander-killing spell.

General answers are appreciated. Specifically, I am also curious if magic resistance plays any role, whether domes help, and best spells to beat the elemental in combat...

It strikes me that the first cast should be offensive in nature versus defense since very many defenses don't save the attacked mage. Opinions?
