If I use Icathian Rain to destroy a monster, can I summon 2 Phoenix with their effects from trash while Icathian Rain is resolving?

Ruling: Yes, you can summon Phoenix cards from trash while Icathian Rain is resolving. When any of Icathian Rain's damage triggers kills a unit, your Phoenixes will trigger and you can pay the cost to play them.

Sequence:

• Icathian Rain resolves and puts 6 triggers on the chain, each dealing 2 damage to a unit
• You choose all targets before the triggers resolve
• Players have a window to react before each trigger resolves
• When any trigger kills a unit, Phoenix effects trigger and you can pay the cost to play them
