Gameplay

Legendary Creature — Elder Dragon

Flying, trample Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.) Instant and sorcery spells you cast from your hand have cascade.

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

2026-03-20wotc

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 (as long as the resulting spell would have lesser mana value than the spell with cascade) but not both halves.

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.
