If Dazzling Aurora reveals and plays a unit after recycling non-units, can Karma Channeler's triggered ability buff that unit?

Ruling: Yes, Karma Channeler can buff the unit played by Dazzling Aurora.

Sequence:

• Aurora resolves, adding the unit to the pending chain, then recycling cards (which triggers Karma)
• Karma's trigger is added to the pending chain after the unit
• The pending chain finalizes in order: the unit is added to the chain first and immediately resolves (enters the battlefield)
• Then Karma's ability is added to the chain, and targets are chosen at this point
• Since the unit is now on the battlefield, it can be targeted by Karma's buff
• Karma's ability resolves, buffing the unit

Nuances:

• If the unit played by Aurora has an on-play trigger (like Deadbloom Predator starting combat), that trigger goes on top of Karma's ability on the chain and resolves first, before Karma's buff
• Targets for triggered abilities are only chosen when the ability is added to the chain, not when it becomes pending
• Items pending to be added to the chain are added in the order they became pending (FIFO), not in reverse order like chain resolution
