Red Elemental Blast and Pyroblast punish their heavy blue base, countering Counterspell and Lorien Revealed or destroying Murmuring Mystic, Augur of Bolas, and Archaeomancer outright. Their Skred can scale with snow permanents to kill our small creatures, so speed and going wide quickly to overload their removal is key. We trim Goblin Tomb Raider and both Chain Lightning for more interaction, since their deck wants a longer grind with Ephemerate value loops that we must avoid letting resolve. Keep the core Rally/Bushwhacker engine intact to close the game before Mulldrifter and card draw take over.
