Heart of Kiran — ruling 1

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.

Heart of Kiran — ruling 2

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.

Heart of Kiran — ruling 3

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.

Heart of Kiran — ruling 4

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

Heart of Kiran — ruling 5

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.

Heart of Kiran — ruling 6

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

Heart of Kiran — ruling 7

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

Heart of Kiran — ruling 8

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.

Heart of Kiran : règles, fonctionnement et interactions (MTG)

Heart of Kiran 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, vigilance Crew 3 (Tap any number of creatures you control with total power 3 or more: This Vehicle becomes an artifact creature until end of turn.) You may remove a loyalty counter from a planeswalker you control rather than pay Heart of Kiran's crew cost.

Complete guide

Heart of Kiran is a legendary Vehicle that offers a unique twist on the crew mechanic, allowing your planeswalkers to join the fray. With its high power, flying, and vigilance, it serves as both a powerful offensive threat and a reliable defender. This card is a staple for decks that want to maximize the utility of their planeswalkers beyond their standard loyalty abilities.

What It Does

Heart of Kiran is a 4/4 legendary Vehicle with Flying and Vigilance. To turn it into a creature, you typically must use the Crew 3 ability by tapping creatures with total power 3 or more. However, Heart of Kiran features a special static ability: instead of tapping creatures, you may remove a loyalty counter from a planeswalker you control to pay the crew cost. This allows you to animate the Vehicle even if you have no creatures on board, provided you have a planeswalker ready to help.

How It Resolves Step by Step

Activating the crew ability follows standard activation rules. First, you announce the ability. Next, you choose your payment method: either tapping creatures or removing a loyalty counter. Once the cost is paid, the ability goes on the stack. When it resolves, Heart of Kiran becomes an artifact creature until the end of the turn. Importantly, because the payment happens during activation, opponents cannot respond by destroying your planeswalker or tapping your creatures to prevent the cost from being paid.

Common Mistakes

One frequent error is thinking that removing a loyalty counter counts as a 'loyalty ability.' It does not. You can activate Heart of Kiran's crew cost by removing a counter even if you have already used a planeswalker's loyalty ability that turn, or even during an opponent's turn to block. Another common mistake is forgetting that 'summoning sickness' applies to Vehicles. Even if you crew Heart of Kiran, it cannot attack unless you have controlled the artifact itself since the beginning of your turn.

When to Play It

Heart of Kiran is best utilized in decks featuring high-loyalty planeswalkers or creatures that benefit from being tapped. Since it has vigilance, it can attack during your turn and still be available to block during your opponent's turn, provided you have a way to crew it again. It is also an excellent target for mana rocks like Sol Ring or Arcane Signet to get it onto the battlefield as early as turn two.

Interaction examples

Early Game Acceleration

Sol Ring

On turn one, you play a land and Sol Ring. Using the two colorless mana from Sol Ring, you cast Heart of Kiran. Although it cannot attack this turn due to summoning sickness, you have established a 4/4 flying blocker very early in the game.

Mana Fixing for Deployment

Arcane Signet

You control Heart of Kiran and an Arcane Signet. During your opponent's turn, you tap Arcane Signet to ensure you have the mana for other spells, while planning to remove a loyalty counter from a planeswalker to crew Heart of Kiran. This allows you to keep your mana rocks and creatures untapped for other utility while still maintaining a powerful 4/4 flying defender.

#9September 29, 2017· 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.
#10September 29, 2017· 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.
#11September 29, 2017· 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.
#12September 29, 2017· 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.
#13February 9, 2017· Wizards of the Coast
Paying Heart of Kiran’s alternative crew cost isn’t a loyalty ability. It can be done even if you’ve already activated a loyalty ability of the planeswalker this turn, and it can be done any time you could activate Heart of Kiran’s crew ability.
