Selesnya Company floods the board quickly via Collected Company, Elvish Mystic, and Llanowar Elves, making sweeping effects valuable. Withering Curse's -2/-2 wipes their mana dorks and small Company hits, and can become a full board wipe via Infusion off Sheoldred, the Apocalypse or Professor Dellian Fel life gain. Ray of Enfeeblement answers Skyclave Apparition or Thalia, Guardian of Thraben cheaply at instant speed. Trim the two Badgermole Cub and one Sentinel of the Nameless City, as their earthbend and Map tokens are less impactful against an opponent racing to overwhelm the board rather than grind card advantage.
