mtg lost caverns card list The of Ixalan (LCI) & Gallery - Deep Wood - The List

Geist of Saint Traft puts his hexproof to good use by being an incredibly powerful attacker that must be removed through a board wipe or combat

Since most of our sweeping effects allow regeneration, this can save a key creature from your mass removal sweepers or your Durnan on other turns when someone casts their own Day of Judgment or Blasphemous Act effect

Thats a huge win

To keep your cards coming back, keep Winter, Cynical Opportunist as your commander

If youre evoking Solitude most of the time, then its a lot less powerful than the other removal options in the format like Swords to Plowshares and Prismatic Ending
