Since they're creatures, wouldn't they have summoning sickness and then can't tap?
I don't need to tap the Treasure Artifact Creatures.
With the following in play: Treasure token +
March of the Machines +
Pitiless Plunderer + (
Blood Artist or Zulaport Cuttthroat) in play:
1.
March of the Machines makes the Treasure Token a 0/0 creature.
2. Next time a player would gain Priority, State-Based Actions are checked.
3. Because of State-Based actions, the 0/0 creature dies.
4. Because a Creature has died, (
Zulaport Cutthroat or
Blood Artist) Drains the opponent for 1 life, and I gain 1 life.
5. Because a Creature has died,
Pitiless Plunderer Creates a treasure, that becomes a 0/0 artifact creature
6. Return to (2), unless all opponents are at 0 life.
7. All opponents are at zero life, they lose the game because of state-based actions. You win the game.
