In Pioneer, Colossus Hammer and Sigarda’s Aid are also legal, but without the help of Puresteel Paladin, it has been challenging to equip Colossus Hammer consistently. Cards like Resolute Strike require a specific creature base, while options like Kazuul’s Toll Collector, Thieving Skydiver or Bruenor Battlehammer are too slow and inefficient. However, with the introduction of a new card from Phyrexia: All Will Be One , Hammer Time may finally have the potential to become a competitive archetype in Pioneer.
Is Seachrome Coast legal in Pioneer? It is listed in the Azorius Hammer deck provided in this article.
Seachrome Coast is reprinted in Phyrexia: All Will Be One, so it will be available in Pioneer.
