Haunted One
Intruder Alarm
Phyrexian Altar

Requires
Xavier Sal, Infested Captain must be on the battlefield. Haunted One must be on the battlefield. Intruder Alarm must be on the battlefield. Phyrexian Altar must be on the battlefield. Xavier Sal, Infested Captain must be your commander. There is at least one counter on a permanent you control except Xavier Sal. Xavier Sal does not have summoning sickness. You control at least one additional nontoken Human, Fungus and/or Pirate that has no more than one +1/+1 counter on it.
Steps
  1. Activate Xavier Sal's first ability by tapping it and removing a +1/+1 counter from the additional nontoken Human, Fungus and/or Pirate if it has one, or any counter from another permanent you control otherwise.
  2. Xavier Sal triggers, causing it and all other creatures you control that share a creature type with it to get +2/+0 and gain undying until end of turn.
  3. Resolve the Xavier Sal ability, causing you to populate.
  4. Activate Phyrexian Altar by sacrificing the additional Human, Fungus and/or Pirate, adding one mana of any color.
  5. When the creature dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
  6. When the creature enters the battlefield, Intruder Alarm triggers, untapping all creatures.
  7. Repeat.
Results
Infinite LTB. Infinite ETB. Infinite colored mana. Infinite sacrifice triggers. Infinite death triggers. Infinite untap of all creatures. Infinite mana creatures you control can produce. Infinitely powerful Humans, Fungi and Pirates you control until end of turn.
