Carte Magic Peacewalker Colossus

Peacewalker Colossus 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

{1}{W}: Another target Vehicle you control becomes an artifact creature until end of turn. Crew 4 (Tap any number of creatures you control with total power 4 or more: This Vehicle becomes an artifact creature until end of turn.)

Complete guide

Peacewalker Colossus is a massive Vehicle that serves as the ultimate flagship for any artifact-themed deck. While it boasts an impressive 6/6 stat line, its true power lies in its ability to mobilize your entire fleet of Vehicles without needing a massive crew.

Awakening the Fleet

Peacewalker Colossus has two ways to become a creature. You can use its Crew 4 ability by tapping creatures with total power 4 or more, or you can use its activated ability for {1}{W} to turn another target Vehicle you control into an artifact creature until end of turn. This unique ability allows you to bypass high crew costs on other Vehicles, turning them into threats for just two mana.

Step-by-Step Resolution

When you activate the Peacewalker Colossus's ability, first, you pay the cost of {1}{W}. Second, you choose another target Vehicle you control. Once the ability resolves, that Vehicle becomes an artifact creature. It retains its printed power and toughness unless another effect specifically overwrites them. Remember, this transition doesn't count as a creature entering the battlefield because the permanent was already there; it simply gained a new type.

Common Pitfalls

A common mistake is forgetting that a Vehicle needs 'summoning sickness' to wear off before it can attack, even if it just became a creature. If you haven't controlled the Vehicle since the start of your turn, it cannot attack or tap for its own abilities unless it has haste. Additionally, note that if a permanent becomes a copy of a Vehicle that is currently a creature, the copy will only be a non-creature Vehicle.

Tactical Timing

To attack with a Vehicle, you must ensure it is a creature before the Declare Attackers step begins. The latest opportunity to activate Peacewalker Colossus's ability for this purpose is during the Beginning of Combat step. Similarly, to block, you must activate the ability no later than the Declare Attackers step so the Vehicle is a creature by the time blockers are declared.

Interaction examples

Mana Efficiency

If you have Arcane Signet on the battlefield, you can tap it to help pay the {1}{W} cost of Peacewalker Colossus's ability. This allows you to turn a high-crew Vehicle into a creature using mana from your artifacts rather than tapping down your defensive creatures.

Sudden Haste

If you play a new Vehicle and use Peacewalker Colossus to turn it into a creature, that new creature cannot attack immediately. However, if you attach Swiftfoot Boots to the newly animated Vehicle, it gains haste and hexproof, allowing it to charge into battle the same turn it was played.

Self-Animation

While Peacewalker Colossus can animate other Vehicles for {1}{W}, it cannot animate itself with that specific ability because it targets 'another' Vehicle. To make the Colossus itself a creature, you must use its Crew 4 ability by tapping other creatures you control.

How it works : Peacewalker Colossus

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    Each Vehicle is printed with a power and toughness, but it's not a creature. If it becomes a creature (most likely through its crew ability), it will have that power and toughness.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    If an effect causes a Vehicle to become an artifact creature with a specified power and toughness, that effect overwrites the Vehicle's printed power and toughness.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    Vehicle is an artifact type, not a creature type. A Vehicle that's crewed won't normally have any creature type.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    Once a player announces that they are activating a crew ability, no player may take other actions until the ability has been paid for. Notably, players can't try to stop the ability by changing a creature's power or by removing or tapping a creature.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    Any untapped creature you control can be tapped to pay a crew cost, even one that just came under your control.

    No other card is named in this ruling.

  6. #6· Wizards of the Coast

    You may tap more creatures than necessary to activate a crew ability.

    No other card is named in this ruling.

  7. #7· Wizards of the Coast

    Creatures that crew a Vehicle aren't attached to it or related in any other way. Effects that affect the Vehicle, such as by destroying it or giving it a +1/+1 counter, don't affect the creatures that crewed it.

    No other card is named in this ruling.

  8. #8· Wizards of the Coast

    Once a Vehicle becomes a creature, it behaves exactly like any other artifact creature. It can't attack unless you've controlled it continuously since your turn began, it can block if it's untapped, it can be tapped to pay a Vehicle's crew cost, and so on.

    No other card is named in this ruling.

  9. #9· Wizards of the Coast

    You may activate a crew ability of a Vehicle even if it's already an artifact creature. Doing so has no effect on the Vehicle. It doesn't change its power and toughness.

    No other card is named in this ruling.

  10. #10· Wizards of the Coast

    For a Vehicle to be able to attack, it must be a creature as the declare attackers step begins, so the latest you can activate its crew ability to attack with it is during the beginning of combat step. For a Vehicle to be able to block, it must be a creature as the declare blockers step begins, so the latest you can activate its crew ability to block with it is during the declare attackers step. In either case, players may take actions after the crew ability resolves but before the Vehicle has been declared as an attacking or blocking creature.

    No other card is named in this ruling.

  11. #11· Wizards of the Coast

    When a Vehicle becomes a creature, that doesn't count as having a creature enter the battlefield. The permanent was already on the battlefield; it only changed its types. Abilities that trigger whenever a creature enters the battlefield won't trigger.

    No other card is named in this ruling.

  12. #12· Wizards of the Coast

    If a permanent becomes a copy of a Vehicle, the copy won't be a creature, even if the Vehicle it's copying has become an artifact creature.

    No other card is named in this ruling.
