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
