Official rulings

Four official rulings apply to Rin and Seri, Inseparable, newest first.

  • If the chosen target is an illegal target by the time Rin and Seri's last ability tries to resolve, the ability won't resolve. You won't gain life.
  • Rin and Seri's first two abilities don't trigger when you cast Rin and Seri.
  • An ability that triggers when a player casts a spell resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
  • The amount of damage Rin and Seri's last ability deals is determined only as that ability resolves. If Rin and Seri is still on the battlefield, it'll count itself.
