Carte Magic Will-o'-the-Wisp

Will-o'-the-Wisp 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

Flying (This creature can't be blocked except by creatures with flying or reach.) {B}: Regenerate this creature. (The next time this creature would be destroyed this turn, instead tap it, remove it from combat, and heal all damage on it.)

Complete guide

Will-o'-the-Wisp is a classic black creature that serves as a persistent defensive wall for a very low investment. By utilizing its cheap regeneration ability, this Spirit can frustrate opponents by repeatedly surviving combat and lethal spells.

A Persistent Defender

Will-o'-the-Wisp is a 0/1 creature with Flying and a built-in regeneration ability. For just one black mana, you can create a 'regeneration shield' that lasts until the end of the turn, ensuring it stays on the battlefield even after taking lethal damage.

How Regeneration Works

When you activate the ability, you aren't bringing the creature back from the graveyard; you are setting up a shield. If the creature would be destroyed by damage or a 'destroy' effect, the shield is used. Instead of dying, the creature remains on the battlefield, becomes tapped, is removed from combat, and all damage is cleared from it.

Common Misconceptions

Regeneration does not save a creature from effects that reduce its toughness to 0 or less, nor does it prevent the creature from being sacrificed or exiled. Because the creature never actually hits the graveyard when the shield is used, it does not count as having 'died' for trigger purposes.

Strategic Timing

You must activate the regeneration ability before the creature is destroyed. In combat, this usually means activating it during the declare blockers step, before combat damage is dealt. You can also stack multiple regeneration shields, though usually only one is needed per instance of destruction.

Interaction examples

Blocking an Aerial Attacker

If your opponent attacks with Ornithopter of Paradise, you can block with Will-o'-the-Wisp because both have Flying. Before damage is dealt, you pay one black mana to regenerate Will-o'-the-Wisp. Even though both have 0 power and won't kill each other, this ensures your Spirit survives any unexpected combat tricks.

Survival vs. Death Triggers

Suppose your opponent casts a spell to destroy Will-o'-the-Wisp while Blood Artist is on the battlefield. You activate the regeneration ability. When the destruction effect resolves, Will-o'-the-Wisp is tapped and saved. Because the Spirit never leaves the battlefield, Blood Artist's ability does not trigger.
