#compleated

Both Compleated and Doubling Season's ability are replacement effects and not triggers, so Elesh Norn doesn't affect them at all.

As for the interaction between Compleated and Doubling Season, you get to choose to apply the counter reduction from Compleated before or after the counter doubling from Doubling Season.

(While Compleated might look like a self-replacement effect, which would have to be applied first, it's actually because it modifies how the planeswalker enters the battlefield, not how the spell resolves.)

Vraska, Betrayal's Sting --- {4}{B}{B/P}

Compleated ({B/P} can be paid with {B} or 2 life. If life was paid, this planeswalker enters with two fewer loyalty counters.)

0: You draw a card and you lose 1 life. Proliferate.

−2: Target creature becomes a Treasure artifact with “{T}, Sacrifice this artifact: Add one mana of any color” and loses all other card types and abilities.

−9: If target player has fewer than nine poison counters, they get a number of poison counters equal to the difference.

Loyalty: 6
