Hi Jason, and welcome to the Mirror Gallery here on Hipsters of the Coast
Once both Archeops are knocked out, they no longer have a way to one hit out of nowhere, so we can Penny loop Chi-Yu and play for the deckout or try to take 6 prizes with Heros Caped Radiant Charizard
There is not much that can block a big Deaths Shadow, however, many of the common removal spells of the format can take care of it, until Lurrus Deaths Shadow and the namesake deck are emblematic for how Magic is played today, interrupt your opponent, play a cheap strong threat and counter whatever your opponent tries to play against you
During each player's main phase, they may roll the six-sided planar die for a chance to take an action: If it lands on the planeswalker symbol the players must planeswalk and move on to the next plane - put the current plane on the bottom of the planar deck and reveal the next one
Additional notes: Stoneforge Mystic builds most likely are running Pre-War Formalwear
