Lazav, l'Hétérogène et Phage, l'Intouchable

J'ai fait un duel contre un ami en Commandeur et j'ai gagné en copiant Phage depuis le cimetière.
Je lui ais déjà expliqué qu'a chaque fois qu'une carte se réfère par son nom, on peut tout aussi bien remplacer par "Cette carte". 
Mais il ne semblait pas convaincu cependant. (Et j'avoue que c'est contre-intuitif.)
Et surtout, quand j'ai essayer de trouvé le Ruling spécifiant cela, je ne l'ai pas trouvé.

Pourriez-vous m'aider s'il vous plait ?
 

Bonjour !

201.4. Text that refers to the object it’s on by name means just that particular object and not any other objects with that name, regardless of any name changes caused by game effects.

201.4a If an ability’s effect grants another ability to an object, and that second ability refers to that first ability’s source by name, the name refers only to the specific object that is that first ability’s source, not to any other object with the same name. This is also true if the second ability is copied onto a new object.

Example: Gutter Grime has an ability that reads “Whenever a nontoken creature you control dies, put a slime counter on Gutter Grime, then create a green Ooze creature token with ‘This creature’s power and toughness are each equal to the number of slime counters on Gutter Grime.’” The ability granted to the token only looks at the Gutter Grime that created the token, not at any other Gutter Grime on the battlefield. A copy of that token would also have an ability that referred only to the Gutter Grime that created the original token.

201.4b If an ability of an object refers to that object by name, and an object with a different name gains that ability, each instance of the first name in the gained ability that refers to the first object by name should be treated as the second name.

Example: Quicksilver Elemental says, in part, “ %U: Quicksilver Elemental gains all activated abilities of target creature until end of turn.” If it gains an ability that says “ %G: Regenerate Cudgel Troll,” activating that ability will regenerate Quicksilver Elemental, not the Cudgel Troll it gained the ability from.
Example: Glacial Ray is an instant with splice onto Arcane that says “Glacial Ray deals 2 damage to any target.” If it’s spliced onto a Kodama’s Reach, that Kodama’s Reach deals 2 damage to the target.
Example: Dimir Doppelganger says “ %1 %U %B: Exile target creature card from a graveyard. Dimir Doppelganger becomes a copy of that card and gains this ability.” Dimir Doppelganger’s ability is activated targeting a Runeclaw Bear card. The Doppelganger becomes a copy of Runeclaw Bear and gains an ability that should be treated as saying “ %1 %U %B: Exile target creature card from a graveyard. Runeclaw Bear becomes a copy of that card and gains this ability.”

Merci.
