When Adaptatron attacks and conquers a field where the defending player has Zhonyas in base and a 2m defender on battlefield, does Zhonyas or Adaptatron trigger first?

Ruling: Zhonyas applies before Adaptatron triggers because scoring happens after combat cleanup.

Sequence:

  • Combat cleanup occurs
  • Zhonyas applies (as a replacement effect, not a triggered ability)
  • Scoring happens
  • Adaptatron triggers

Nuances:

  • Zhonyas is a replacement effect, not a triggered ability, so it doesn't use the chain and can apply in between resolutions or cleanups
