Wildsear, Scouring Maw is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
Trample Enchantment spells you cast from your hand have cascade. (Whenever you cast an enchantment spell from your hand, 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.)
Complete guide
Wildsear, Scouring Maw is a powerful Elemental Wolf that turns your enchantments into a relentless wave of value. By granting cascade to enchantment spells cast from your hand, it ensures your board presence grows rapidly with every spell played. This legendary creature is a cornerstone for any deck looking to overwhelm opponents with magical auras and global effects.
How Cascade Works with Wildsear
When Wildsear, Scouring Maw is on the battlefield, every enchantment spell you cast from your hand gains the cascade keyword. This triggered ability triggers exactly when you finish the process of casting the spell. You then exile cards from the top of your library until you find a nonland card with a lower mana value than the enchantment you just cast. You have the choice to cast that card for free, while all other exiled cards are returned to the bottom of your library in a random order.
The Resolution Process
Cascade resolves before the original enchantment spell that triggered it. If you choose to cast the card found via cascade, that new spell goes on top of the stack and will resolve first. It is important to note that the mana value of your enchantment is determined solely by its printed mana cost; cost reducers or additional costs do not change this number. Even if your opponent counters your original enchantment, the cascade trigger still resolves because it exists independently on the stack.
Common Mistakes to Avoid
A frequent error involves the source of the spell: Wildsear only grants cascade to spells cast from your hand. Enchantments cast from your graveyard, library, or command zone will not trigger cascade. Additionally, if you exile a card with an 'X' in its cost, you must choose 0 for X when casting it for free. Lastly, remember that the spell you cast must have a lower mana value than the original spell; you cannot use a low-cost enchantment to cascade into a high-cost half of a split card if the total mana value of that half is higher.
Strategic Timing
Wildsear is best played when you have a hand full of enchantments to follow up immediately. Because it has trample and a solid power/toughness ratio, it serves as both a value engine and a significant combat threat. Be wary of removal; while removing Wildsear in response to a spell being cast won't stop a trigger that has already happened, your opponent can prevent future cascades by removing Wildsear before you cast your next enchantment.
Interaction examples
With Wildsear, Scouring Maw on the battlefield, you cast Roaming Throne and choose 'Elemental' or 'Wolf'. Later, when you cast an enchantment spell from your hand, Wildsear's cascade ability triggers. Because Roaming Throne sees a triggered ability of a creature of the chosen type, Wildsear's cascade triggers a second time. You will resolve two separate cascade sequences, potentially casting two free spells before your original enchantment resolves.
You have Wildsear, Scouring Maw in play and cast a 5-mana enchantment from your hand. The cascade trigger initiates, and you exile cards until you hit Solemn Simulacrum. Since the Golem's mana value (4) is less than your enchantment (5), you may cast it for free. The Solemn Simulacrum enters the battlefield, its land-search ability triggers and resolves, then the Golem itself is fully on the board, and finally, your original 5-mana enchantment resolves.

Once you announce that you're casting a spell, players can't take actions until you've finished casting it. Causing Wildsear to leave the battlefield after you've cast an enchantment spell from your hand won't stop that spell's cascade ability from resolving.

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.
No other card is named in this ruling.
- #11· Wizards of the Coast
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.
