Seismic AssaultI've always been partial to Seismic Assault (along with its 
ancestor) and am hoping it has a brief surge of relevance in the newly-announced Extended format. Oh, that was 
quite an announcement, huh? We, the Magic community, gliding along, la-di-da, Archenemy, yay, M11 spoilers, feelin' groovy, tra-la-la BAM!  LAVA FIST!  And then 24 hours of speculators chain-chugging foul energy drinks while trying to lock up every underpriced Mistbind Clique they could lay hand or mouse on.
Having never really had bandwidth for Extended, I like the change.  Previously, if an Extended GP happened in my backyard I would not play in the main event.  With the more digestible card pool, I might.
