The 2 combo pieces

What must be in place

An opponent controls a creature with toughness less than twenty.

How to execute it

  1. Cast Star of Extinction by paying {5}{R}{R}, destroying target land, and then dealing 20 damage to each creature and each planeswalker.
  2. For each creature opponents control that is dealt excess damage, Fall of Cair Andros triggers, creating a 0/0 Army if you dont control one, and putting a number of +1/+1 counters on an Army you control equal to the excess damage.
