The idea is to play this in a Black deck that has enough mana with Cabal Coffers and Urborg, Tomb of Yawgmoth or Nykthos, Shrine to Nyx or Caged Sun to fill this out with tons of X mana to make all of that mana and force enough for your foes to lose life, discard their hand and be denuded of their stuff and then you can, slowly win the game from there after removing their life, hand and stuff so that you have a slower game win from there with anything like Commander damage or finishing off someone with a lower post-Torment life
"Magnezone-EX" 35/106 is a different card name to "Magnezone ex" 065/198, so you could have 4 of each in 1 deck
