When Darius Trifarian is in play and you cast Falling Star or Icathian Rain, what order do Darius's triggered ability and the reflexive triggers go on the stack?

Ruling: When the spell resolves, Darius's triggered ability and the reflexive triggers all trigger at the same time, so you choose the order they go on the stack.

Sequence:

• Cast Falling Star or Icathian Rain
• The spell resolves
• Darius's "when you play a spell" trigger and the reflexive triggers all trigger simultaneously
• You choose the order to put them on the stack
