Nekuroji, Who Died Twice

Vigilance, lifelink, menace.
Instant cards in your hand have splice onto arcane.
Its splice onto arcane cost is equal to its mana cost reduced by {1}.
When Nekuroji dies, if it had no counters on it, return it to the battlefield under its owner's control with a finality counter and two +1/+1 counters on it.
{w}{u}{b}: Until end of turn, you may play target Spirit or Arcane card from your graveyard.
"Before I died, everyone I knew was still alive. I've died two times, so far."
