If you control no creatures as Kin-Tree Invocation resolves, you’ll put a 0/0 token onto the battlefield. Unless something else is raising its toughness above 0, it will immediately be put into its owner’s graveyard and then cease to exist. Any abilities that trigger when a creature enters the battlefield or dies will trigger.

The value of X is determined only once, as Kin-Tree Invocation resolves. The power and toughness of the Spirit Warrior token doesn’t later change if the greatest toughness among creatures you control changes.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
