Sméagol, Helpful Guide + Dúnedain Rangers + Zendikar's Roil + Ashnod's Altar

Sméagol, Helpful Guide
Dúnedain Rangers
Zendikar's Roil
Ashnod's Altar

Requires
Sméagol, Helpful Guide must be on the battlefield. Dúnedain Rangers must be on the battlefield. Zendikar's Roil must be on the battlefield. Ashnod's Altar must be on the battlefield. You don't control a Ring-bearer. You have a land card in hand.
Steps
  1. Play a land card, triggering Dúnedain Rangers and Zendikar's Roil.
  2. Resolve the Zendikar's Roil trigger, creating a 2/2 Elemental creature token.
  3. Resolve the Dúnedain Rangers trigger, causing the Ring to tempt you, and causing the Elemental token to become your Ring-bearer.
  4. Sméagol triggers.
  5. Holding priority, activate Ashnod's Altar by sacrificing the Elemental, adding cc.
  6. Resolve the Sméagol trigger, causing an opponent to reveal cards from the top of their library until they reveal a land card, then causing you to put the land onto the battlefield tapped under your control, and your opponent to put all other revealed cards into their graveyard.
  7. When the land enters the battlefield, Dúnedain Rangers and Zendikar's Roil trigger.
  8. Repeat from step 2.
  9. NOTE: This combo can be stopped if an opponent runs out of lands in their library, so it is recommended to alternate opponents in between cycles to maximize the amount of iterations.
Results
Near-infinite colorless mana. Near-infinite death triggers. Near-infinite ETB. Near-infinite landfall triggers. Near-infinite LTB. Near-infinite mill. Near-infinite sacrifice triggers. Put all land cards from your opponents' libraries onto the battlefield tapped under your control.
