Assassin MP after Dark Quarrel cancels attacks

[Gamling the Old]

If I cancel 2 attacks of Assassin and kill the last one, do I get the 2 MP?

The argument in favor:

CoE rule 3.v states: "If at least one strike was assigned and all assigned strikes were defeated, the creature is defeated and placed in the marshalling point pile of the defending player... If any of the strikes were not defeated or if no strikes were assigned, the creature is immediately discarded."

A canceled attack is not an "assigned" strike — it simply doesn't happen. Only strikes that were actually faced need to be defeated for the creature to count as defeated. Since the one remaining (non-canceled) strike was defeated, Assassin is fully defeated, and the kill MP is correctly awarded. Defeating all 3 original attacks is not required once 2 have been legitimately canceled.

Tapping to cancel a strike doesnt work (as the strike is assigned for that),

DEFEATING AN ATTACK
An attack by a hazard creature is defeated if it is not a detainment attack and all of its strikes directed against (i.e., assigned to) a company are defeated.

If a hazard creature has multiple attacks, each must be defeated in order for the creature to be defeated.

If even one of the strikes was canceled or ineffectual, the attack is not defeated. If the attack is canceled, the attack is not defeated. A canceled attack has no effect on the defending company (though the company is considered in its history to have faced it). A detainment attack from a creature is never defeated and the creature’s card is always discarded after the attack is resolved.
