Triage analysis

Clarified summary

Elesh Norn, Mother of Machines does not suppress enter-the-battlefield triggers of permanents controlled by opponents.

Oracle text

“Permanents entering don't cause abilities of permanents your opponents control to trigger.”

Investigation findings

The authoritative export explicitly marks this suppression clause unsupported/unknown, while the separate additional-trigger clause is supported. The report is therefore a known coverage gap requiring general trigger-suppression infrastructure, not a defect in an AST that claims to implement the clause. No exact duplicate was found.

Acceptance criteria

• While Elesh Norn is controlled, permanents entering do not cause abilities of opponents' permanents to trigger.
• Non-ETB trigger causes remain unaffected.
• The controller's own applicable ETB triggers still trigger an additional time.
• Multiple replacement/suppression effects compose without creating or deleting unrelated triggers.

Classifier analysis

Verdict: unsupported_aspect
Matched clause: Opponents' permanents' ETB-trigger suppression (supported: false)
Reasoning: The exact reported sentence is exported as an unsupported unknown ability; only Elesh Norn's separate trigger-doubling sentence claims support.
