The 5 combo pieces

What must be in place

Jace's Archivist and Bloom Tender do not have summoning sickness.
A player has at least one card in their hand.

How to execute it

  1. Activate Bloom Tender by tapping it, adding at least {U}{R}{G}.
  2. Activate Jace's Archivist by paying {U} and tapping it, causing each player to discard their hand and draw cards equal to the greatest number of cards discarded by a single player this way.
  3. Xyris triggers once for each card your opponent draw, and Kozilek triggers if it was discarded.
  4. Resolve the first Xyris trigger, creating a 1/1 Snake creature token.
  5. The Snake enters the battlefield, triggering Intruder Alarm, untapping all creatures.
  6. Activate Bloom Tender by tapping it, adding at least {U}{R}{G}.
  7. Repeat from step 4 for each remaining Xyris trigger.
  8. Resolve the Kozilek trigger from step 3, if applicable, causing you to shuffle your graveyard into your library.
  9. Repeat from step 2.
