Momentous Fall copy spell Uyo, Silent Prophet darksteel colossus magic

[Urza]

I control a Uyo, Silent Prophet

Other players casts a Momentous Fall sacrificing his darksteel colossus

I use Uyo's ability to copy Momentous Fall. Do I also gain 11 life and draw 11 cards, or does it end up being 0 life and 0 cards because of that additional cost to sacrifice which I assume I cannot pay?

[Arix]

You'll gain 11 and draw 11. The copy uses the same values as the original.

If an effect of the copy refers to objects used to pay its costs, it uses the objects used to pay the costs of the original spell or ability.

With level 4 echo mage could you copy momentous fall twice and gain 22 life and draw 22 cards?

With level 4 echo mage could you copy momentous fall twice and gain 22 life and draw 22 cards?

Yes, because 11+11=22
