Spider-Man, Peter Parker 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

Flying (This creature can't be blocked except by creatures with flying or reach.) Whenever you gain life, put a +1/+1 counter on target creature you control. It gains indestructible until end of turn. (Damage and effects that say "destroy" don't destroy it.)

Complete guide

Spider-Man, Peter Parker is a powerful Legendary Creature that turns every instance of life gain into a permanent buff and temporary protection. With a respectable five-mana cost, he serves as a reliable engine for White-based defensive or aggro strategies. By providing both a +1/+1 counter and indestructible, he ensures your board presence scales while remaining resilient against board wipes.

How He Navigates the Battlefield

Spider-Man, Peter Parker features a triggered ability that activates every time you gain life. It is important to note that this triggers once per life gain event, regardless of how much life is actually gained. When the ability triggers, you target a creature you control to receive a +1/+1 counter and gain the indestructible keyword until the end of the current turn.

Step-by-Step Resolution

First, an effect causes your life total to increase. Second, Spider-Man's ability triggers and is put on the stack, at which point you must choose a legal target creature you control. Third, when the ability resolves, the counter is placed first and the indestructible status is applied second. If the target becomes illegal before the ability resolves, the entire ability fails and you gain no counters or protection.

Common Mistakes to Avoid

A common misconception is that gaining 5 life at once provides five counters; it only provides one counter because it was a single event. Additionally, remember that indestructible only lasts until the end of the turn, so your creatures will be vulnerable again during your opponent's next turn. Finally, Spider-Man can target himself with his own ability, allowing him to grow and protect himself.

When to Deploy Spider-Man

You should play Spider-Man when you have an established board or immediate ways to gain life. Because his ability provides indestructible, he is best used defensively to discourage opponents from using removal spells or offensively to allow a creature to attack safely into a dangerous block.

Interaction examples

Buffing the Golem

Solemn Simulacrum

If you have an effect that gains you life while both creatures are on the battlefield, you can target Solemn Simulacrum with Spider-Man's trigger. Solemn Simulacrum will receive a +1/+1 counter, making it a 3/3, and it will gain indestructible. This allows it to serve as a persistent blocker that still provides you a card draw later whenever it finally dies after the turn ends.

Doubling Down with the Throne

Roaming Throne

As Roaming Throne enters the battlefield, you choose the creature type 'Spider' or 'Human'. Because Spider-Man, Peter Parker is both, any time you gain life, his ability triggers an additional time. You can choose the same creature for both targets or two different creatures. Each target will receive a +1/+1 counter and gain indestructible for the turn, effectively doubling the value of every life gain spell you cast.
