When Promising Future banishes units with 'when you play me' triggers, at what point do those triggers enter the chain and in what order do they resolve relative to other cards banished by Promising Future?

Ruling: When units with 'when you play me' triggers are played via Promising Future, their triggers enter the chain as pending items immediately after each unit resolves. These triggers are then finalized after all other Promising Future cards are finalized, and they resolve before the other Promising Future cards.

Sequence:

• Promising Future fully resolves
• Players finalize their banished cards in order (A, B, C, D)
• When a unit with a trigger is finalized, it resolves immediately and its trigger enters the chain as pending
• After all Promising Future cards are finalized, the unit triggers are finalized
• The unit triggers resolve first (in reverse order of when they were added), then the remaining Promising Future cards resolve

Nuances:

• The player who played Promising Future finalizes their card last, not first
• Unit triggers enter the chain pending when the unit resolves, not when it's finalized
• In the example, final chain order from top to bottom is: Pit Rookie trigger (full), Riptide Rex trigger (full), Meditation (full), Charm (full)
