How does Icathian Rain resolve, particularly regarding the timing of target selection, reactions, and what happens if targets become invalid?

Ruling: Icathian Rain is played, players can react, then it resolves by putting 6 reflexive triggers on the chain. You pick targets for all 6 triggers at once (paying deflect costs if applicable), then each trigger resolves individually with reaction windows between them. Once targets are selected, they cannot be changed.

Sequence:

• Play Icathian Rain
• Players can react
• Icathian Rain resolves, putting 6 reflexive triggers on the chain
• Pick targets for all 6 reflexive triggers
• Pay additional cost for each trigger targeting an enemy unit with deflect
• Players can react
• First trigger resolves dealing 2 damage
• Players can react
• Second trigger resolves dealing 2 damage
• (Continue pattern for remaining 4 triggers)

Nuances:

• If units are bounced before Icathian Rain resolves (step 2), the caster must choose from remaining valid targets when selecting targets for the reflexive triggers
• Once targets are selected for the reflexive triggers, they cannot be changed even if the target becomes invalid
• If a target is removed after being selected, the trigger targeting it simply does nothing (whiffs)
• You can target the same unit with multiple triggers, even if one trigger would kill it
• If you target your own unit with deflect, you must pay the deflect cost
