wotc
When the cascade ability resolves, you must exile cards. The only optional part of the ability is whether or not you cast the last card exiled.
wotc
You exile the cards face up. All players will be able to see them.
wotc
If a spell has multiple instances of cascade, each one triggers separately.

Notes
Vault entries gain a personal note when you add this card to your binder — pull location, sleeve type, trade history. Sign in to start tracking.
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.
wotc
A spell's mana value is determined only by its mana cost. Ignore any alternative costs, additional costs, cost increases, or cost reductions.
wotc
As the activated ability resolves, it creates a continuous effect that won't begin to apply until the targeted player starts casting a spell this turn. It applies to that spell and the timestamp of that effect is the time that the spell was put on the stack.
wotc
The mana value 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.
wotc
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.
wotc
If a spell with cascade is countered, the cascade ability will still resolve normally.
wotc
If the card has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.
wotc
Some cards, such as modal double-faced cards or adventurer cards, can be cast as one of two different spells, each with different mana costs. If the card you're casting as the cascade ability resolves is one of those cards, you may choose to cast it as either of those spells that has a lower mana value than the spell with cascade.
