Enigma Sfinx

Cascade triggers when you cast the spell, meaning that it resolves before that spell. If you end up casting the exiled card, it will go on the stack above the spell with cascade.

If a spell with cascade is countered, the cascade ability will still resolve normally.

If the last card exiled is a card with an Adventure, you may only cast the spell as an Adventure if that spell has a lesser mana cost than the spell with cascade.

If you cast a card “without paying its mana cost,” you can’t choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, you must pay those to cast the card.

The converted mana cost of a split card is determined by the combined mana cost of its two halves. If cascade allows you to cast a split card, you may cast either half but not both halves.

After Enigma Sphinx’s middle ability triggers, if Enigma Sphinx is removed from your graveyard in response, it won’t be put into your library.

If you cast the last exiled card, you’re casting it as a spell. It can be countered. If that card has cascade, the new spell’s cascade ability will trigger, and you’ll repeat the process for the new spell.

If you control an Enigma Sphinx that’s owned by another player, it’s put into that player’s graveyard from the battlefield, so Enigma Sphinx’s middle ability won’t trigger.
