Requires
Ratadrabik of Urborg must be on the battlefield. Adrix and Nev, Twincasters must be on the battlefield. Duke Ulder Ravengard must be on the battlefield. You have at least three opponents.
Steps
  1. At the beginning of your combat phase, Duke Ulder Ravengard triggers, giving Adrix and Nev haste and myriad until end of turn.
  2. Declare Adrix and Nev as an attacker.
  3. Adrix and Nev's myriad ability triggers, creating two token copies of Adrix and Nev that are tapped and attacking each opponent.
  4. Put all Adrix and Nev tokens into your graveyard due to the legend rule.
  5. When the Adrix and Nev tokens die, Ratadrabik of Urborg triggers that many times.

  7. Repeat step 6 for each remaining trigger.
