Went 7-1 in MTG Arena. Actually had some success early on with the Seismic Shifts, but after a few games it became clear that Run Amok fit better, especially by giving Valduk the toughness to live through combats. Radiating Lightning was also subbed out since this format has so much meat, and I was just dodging all the low-toughness beaters in races anyway.

Probably should have also dropped The Flame of Keld when I dropped the Lightning, since the deck isn't really fast enough to make it important, but as almost my only source of cards I wanted to keep it around.
