Sweet-Gum Recluse

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

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.

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.

Due to a 2021 rules change to cascade, not only do you stop exiling cards if you exile a nonland card with lesser mana value than the spell with cascade, but the resulting spell you cast must also have lesser mana value. Previously, in cases where a card's mana value differed from the resulting spell, such as with some modal double-faced cards or cards with an Adventure, you could cast a spell with a higher mana value than the exiled card.

You exile the cards face up. All players will be able to see them.

A permanent that wasn't a creature as it entered the battlefield this turn but is currently a creature can be chosen as a target of Sweet-Gum Recluse's last ability.
