The win conditions are most often Hallowed Spiritkeeper or Cavalier of Flame, and it wins by putting creatures or lands into the graveyard
Right after activating Mazes Ends ability, the card checks if you control 10 Gates, and if you do, you immediately win the game
Pioneer strikes a nice balance between those elements, making it an optimal format for those who dont like either extreme
Honestly, really interested in seeing how this game's meta will develop
