When you move a unit on your turn, does it happen immediately without creating a chain, preventing opponents from responding with Reaction spells before the move resolves?

Ruling: Normal movement resolves immediately and does not create a chain, so opponents cannot respond with Reaction spells before the move completes.

Nuances:

• If a unit has a "when I move" trigger, then a chain is created
• Moving to a battlefield starts a showdown (which does create opportunities for responses)
