Carte Magic Wilt in the Heat

Wilt in the Heat 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

This spell costs {2} less to cast if one or more cards left your graveyard this turn. Wilt in the Heat deals 5 damage to target creature. If that creature would die this turn, exile it instead.

Complete guide

Wilt in the Heat is a powerful Boros instant that turns graveyard movement into efficiency. It offers high-impact creature removal while ensuring that the target is permanently removed from the game via exile.

Cost Reduction Mechanics

The primary strength of Wilt in the Heat lies in its ability to cost only {R}{W}. This reduction occurs if any card has left your graveyard earlier in the turn for any reason. This includes cards being exiled to pay a cost, being returned to your hand, or being shuffled back into your library. Note that the mana value remains 4 regardless of what you actually pay.

Resolving the Damage and Exile

When Wilt in the Heat resolves, it deals 5 damage to its target. Simultaneously, it applies a replacement effect to that creature. If the creature would die at any point later in the same turn—whether from this spell's damage or other sources—it is moved to the exile zone instead of the graveyard.

Strategic Timing

You should aim to trigger the cost reduction before casting this spell to maintain mana for other plays. Because it creates a replacement effect that lasts until the end of the turn, it is exceptionally effective against creatures with 'dies' triggers or recursion abilities, as those effects will not trigger when the creature is exiled.

Common Mistakes

A common error is assuming a card entering your graveyard from elsewhere triggers the discount; the card must specifically leave the graveyard. Additionally, remember that the exile effect only applies if the creature would die. If the creature is bounced to a player's hand or shuffled into a library, Wilt in the Heat does not intervene.

Interaction examples

Exiling a Menace

You cast Wilt in the Heat targeting a 4/4 creature. The spell deals 5 damage, which is marked as lethal. As the creature attempts to go to the graveyard, the replacement effect intervenes and exiles the card instead.

Interaction with Chaos Warp

If you use Chaos Warp to shuffle a card from your graveyard into your library, Wilt in the Heat now costs {2} less to cast. You can then spend {R}{W} to deal 5 damage to a creature and ensure it gets exiled if it dies.

Cleanup after Generous Gift

After you use Generous Gift to destroy a permanent, your opponent receives a 3/3 Elephant token. Wilt in the Heat can be used to deal 5 damage to that token. While tokens aren't cards, the replacement effect still exiles the token, preventing any 'dies' triggers before the token ceases to exist.

How it works : Wilt in the Heat

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions (such as that of Wilt in the Heat's first ability). The mana value of the spell is determined by only its mana cost, no matter what the total cost to cast that spell was.

    No other card is named in this ruling.
