Carte Magic Shrill Howler // Howling Chorus

Shrill Howler // Howling Chorus 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.

01

Official card text

Creatures with power less than this creature's power can't block it. {5}{G}: Transform this creature. Creatures with power less than this creature's power can't block it. Whenever this creature deals combat damage to a player, create a 3/2 colorless Eldrazi Horror creature token.

Complete guide

Shrill Howler is a menacing Werewolf Horror that uses its physical presence to intimidate smaller blockers. Once it transforms into Howling Chorus, it not only retains its evasive properties but also begins spawning an army of Eldrazi horrors.

Evaluating Blockers

Both Shrill Howler and its transformed side, Howling Chorus, share a static ability: creatures with power less than their power cannot block them. This check happens only once, at the very moment the defending player declares their blockers. If Shrill Howler has 2 power, a creature with 1 power cannot be assigned as a blocker.

Transforming and Triggering

For a cost of five generic and one green mana, Shrill Howler transforms into Howling Chorus. This new form possesses a triggered ability that goes on the stack whenever it successfully deals combat damage to a player. Upon resolution, you place a 3/2 colorless Eldrazi Horror creature token onto the battlefield.

Common Mistakes

The most frequent error involves changing power after blockers are set. If an opponent blocks Shrill Howler with a legal blocker, and you subsequently increase Shrill Howler's power, the block remains valid. The 'can't block' check does not re-evaluate after the declare blockers step has passed.

When to Play

Play Shrill Howler when you can take advantage of its evasion to chip away at your opponent's life total or force them to lose larger creatures in combat. It is best to activate the transformation during your opponent's end step or when you have excess mana to ensure you can start generating Eldrazi Horror tokens on your next attack.

Interaction examples

Intimidating Small Creatures

You attack with Shrill Howler (2 power). Your opponent attempts to block with Sakura-Tribe Elder (1 power). Because 1 is less than 2, the block is illegal. Sakura-Tribe Elder cannot be declared as a blocker.

The Moment of Blocking

You attack with Shrill Howler (2 power). Your opponent blocks with Solemn Simulacrum (2 power). Because 2 is not less than 2, this is a legal block. Even if you cast a spell to increase Shrill Howler's power to 4 after the block is made, Shrill Howler remains blocked by the Golem.

Expanding the Chorus

After transforming your creature into Howling Chorus, it attacks and is not blocked. It deals 3 damage to the player. The triggered ability goes on the stack and resolves, creating a 3/2 Eldrazi Horror creature token. This token does not share the 'can't be blocked' ability of its creator.
