Mikaeus, the Unhallowed
Crystalline Crawler
Viscera Seer

Requires
All permanents on the battlefield.
Steps

  2. Repeat step 1 until Crystalline Crawler has no +1/+1 counters on it.
  3. Activate Viscera Seer by sacrificing Crystalline Crawler.
  4. Crystalline Crawler dies, triggering its undying ability, returning it to the battlefield with a +1/+1 counter on it.
  5. Resolve the Viscera Seer ability, causing you to scry 1.
  6. Repeat.
Results
Infinite colored mana. Infinite ETB. Infinite LTB. Infinite death triggers. Infinite sacrifice triggers. Infinite scry 1.
