Aihe: Ashen Rider opponentin kontrollissa ja "dies" -trigger

[Pifase]

Minulla on pöydässä Ashen Riderin. Vastustaja ottaa sen kontrolliin pelattuaan Conquering Manticoren pöytään. Combat tapahtuu ja toisessa mainphasessaan vastustaja säkkää Ashen Riderin säkkiabilityyn X. Ashen Rider menee mun graveyardille kuollessaan.

Eikö Ashen Riderin dies -triggeri tapahdu vasta, kun se menee mun graveyardilla? Mun ymmärtääkseni magicissa ei ole "tämä olisi kuolemassa mun hallussa" -triggeriä
Säännöissä: "700.4. The term dies means “is put into a graveyard from the battlefield.”

Kenen "dies" -triggeri, millä perusteella ja kuka päättää triggerin kohteen?

[Retardi]

"Dies" triggerissä relevanttia on, kenen kontrollissa creature oli kuollessaan, triggeri on siis vastusjan.

Tahtoisin nähdä myös sääntökohdat tähän.

603.6c. Leaves-the-battlefield abilities trigger when a permanent moves from the battlefield to another zone, or when a phased-in permanent leaves the game because its owner leaves the game. These are written as, but aren't limited to, "When [this object] leaves the battlefield, . . ." or "Whenever [something] is put into a graveyard from the battlefield, . . . ." An ability that attempts to do something to the card that left the battlefield checks for it only in the first zone that it went to. An ability that triggers when a card is put into a certain zone "from anywhere" is never treated as a leaves-the-battlefield ability, even if an object is put into that zone from the battlefield.

603.6d. Normally, objects that exist immediately after an event are checked to see if the event matched any trigger conditions. Continuous effects that exist at that time are used to determine what the trigger conditions are and what the objects involved in the event look like. However, some triggered abilities must be treated specially. Leaves-the-battlefield abilities, abilities that trigger when a card leaves a graveyard, abilities that trigger when a permanent phases out, abilities that trigger when an object that all players can see is put into a hand or library, abilities that trigger specifically when an object becomes unattached, abilities that trigger when a player loses control of an object, and abilities that trigger when a player planeswalks away from a plane will trigger based on their existence, and the appearance of objects, prior to the event rather than afterward. The game has to "look back in time" to determine if these abilities trigger.
