Conduit of Storms // Conduit of Emrakul

You’ll add mana at the beginning of the next main phase whether or not Conduit of Storms (or Conduit of Emrakul) is still on the battlefield.

If Conduit of Storms attacks and you transform it into Conduit of Emrakul in response, you’ll add {R}, not {C}{C} and not {C}{C}{R}.
