Heart of Kiran, the flagship of the renegade faction on Kaladesh, and a strong contender for flagship card of the set as well. This Vehicle is unusual in that it has not one, but two ways to crew it. The first, normal way is to tap creatures with a combined power of 3 or greater. But what if you’re in a bit of a pinch and find yourself creatureless? Planeswalkers can fill in as well! All for the low, low cost of one loyalty counter, you can send a planeswalker behind the wheel.
Bear in mind this is a crew ability, not a loyalty ability – so you can do something like activate Saheeli Rai‘s first ability to scry and damage your opponent, then immediately remove the loyalty counter you just gained to crew Heart of Kiran and attack. You can remove counters to crew on your opponent’s turn as well (perhaps to protect said planeswalker), and effects like Deadlock Trap, that shut off planeswalkers, won’t stop them from being able to crew the Heart. On the other hand, if Heart of Kiran is prevented from activating abilities (such as with Modern sideboard all-star Stony Silence), then you can’t crew it with creatures or planeswalkers.
