Does moving a unit to your own battlefield start a chain (when there are no on-play effects, move effects, or end phase effects)?

Ruling: Moving a unit to a battlefield you already control does not start a chain, and your opponent does not get priority to react.

Sequence:

• Moving does not use the chain
• Since you aren't contesting the battlefield, no showdown starts
• The opponent doesn't get priority at any time during this process

Nuances:

• Focus is only relevant during showdowns, not during the moving process
• This applies specifically when moving to a battlefield you currently control (not contesting it)
