If Icathian Rain's second shot kills Machine Evangel, does its Deathknell trigger immediately or after all shots resolve?

Ruling: The Deathknell trigger resolves immediately when Machine Evangel dies, before the remaining Icathian Rain shots resolve. The tokens created by Deathknell will be played and fully resolve before the remaining shots continue.

Sequence:

• Icathian Rain is played
• All 6 targets are chosen
• First two shots kill Machine Evangel
• Deathknell triggers and Recruit tokens are played and fully resolve
• The 4 remaining shots resolve (targeting the units chosen in step 2)

Nuances:

• All targets for Icathian Rain are chosen when it resolves, before any shots are fired
• You cannot target the newly created tokens from Deathknell with the remaining shots, since targets were already chosen
• The game finalizes cleanup after each trigger, which is why Deathknell resolves completely before continuing
