Taylor controls a Traveling Merchant, Ahri, Inquisitive, and Diana, Lunari in their base. Nicole controls Teemo, Strategist at a battlefield. Taylor moves all three of their units into the battlefield controlled by Nicole. At the appropriate time, Taylor discards a card for Traveling Merchant’s trigger, pays [1] to finalize Diana, Lunari’s trigger, and chooses Teemo, Strategist as the target for Ahri, Inquisitive’s ability. Nicole chooses Traveling Merchant as the target for Teemo, Strategist’s ability. In what order should all of these triggers resolve? A. Traveling Merchant, Diana, Teemo, Ahri B. Traveling Merchant, Teemo, Ahri, Diana C. Diana, Traveling Merchant, Ahri, Teemo D. Diana, Traveling Merchant, Teemo, Ahri E. Traveling Merchant, Ahri, Teemo, Diana

B — Traveling Merchant, then Teemo, then Ahri, then Diana.

Two separate Chains here, which is why Traveling Merchant leads. All three units moved in one Standard Move (one game action), so Traveling Merchant's "When I move" trigger goes on the Chain right then, and because a Showdown can't open while the Chain is non-empty (Rule 462), it finalizes and resolves before combat ever starts — that's the discard/draw, before anything else.

Then the Combat Showdown's triggers stack in this order (bottom to top): Diana's "when a showdown begins here" is the first placed, since start-of-showdown effects happen before Attacker/Defender exist (466.2.b); Ahri's attack trigger is placed next as the Attacker's, and Teemo's defend trigger is placed last as the Defender's (466.2.d.1). Newest resolves first, so Teemo resolves before Ahri, and Diana resolves dead last.
