Cascade and cards like Hypergenesis

[Ghostship]

If I play a card with cascade, lets say Violent Outburst, and the first card removed isHypergenesis, do I get to play it or do i keeping removing cards?

You may play it if you so choose. It might have no mana cost, but cascade allows you to play the spell without paying its mana cost. So you can play it even though it has no cost.
