The 3 combo pieces

What must be in place

Jegantha does not have summoning sickness.

How to execute it

  1. Activate Jegantha by tapping it, adding {W}{U}{B}{R}{G} that cannot be spent to pay generic mana costs.
  2. Activate Sisay by paying {W}{U}{B}{R}{G}, searching your library for a legendary creature card with mana value less than Sisay's power and putting it onto the battlefield.
  3. When the legendary creature enters the battlefield, Intruder Alarm triggers, untapping all creatures.
  4. Repeat.
