Underworld Breach + Squandered Resources + Splendid Reclamation + Windfall

Underworld Breach
Squandered Resources
Splendid Reclamation
Windfall

Requires
Underworld Breach must be on the battlefield. Squandered Resources must be on the battlefield. Splendid Reclamation must be in hand, or in the graveyard. Windfall must be in hand, or in the graveyard. A player has at least six cards in hand, not including Windfall if its in your hand. You control at least seven lands, of which one can tap to produce and another can tap to produce . If Windfall is in your graveyard, you have three other cards in your graveyard excluding it and Splendid Reclamation if it's in your graveyard.
Steps
  1. Activate Squandered Resources by sacrificing at least seven lands, adding 5.
  2. Cast Windfall either from your hand by paying 2, or from your graveyard for its escape cost by paying 2 and exiling three nonland cards except Splendid Reclamation from your graveyard, causing each player to discard their hand and draw cards equal to the greatest number a player discarded this way.
  3. Cast Splendid Reclamation from your graveyard for its escape cost by paying 3 and exiling three nonland cards except Windfall from your graveyard, returning all land cards from your graveyard to the battlefield tapped.
  4. Repeat.
  5. Depending on the number of cards in a player's hand and/or in your graveyard when Windfall resolves, you may be able to omit casting it during an iteration.
Results
Infinite draw triggers for all players. Infinite looting for all players. Infinite self-discard triggers for all players. Near-infinite landfall triggers. Near-infinite magecraft triggers. Near-infinite storm count.
