Kibo, Uktabi Prince 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

: Each player creates a colorless artifact token named Banana with ", Sacrifice this token: Add or . You gain 2 life." Whenever an artifact an opponent controls is put into a graveyard from the battlefield, put a +1/+1 counter on each creature you control that's an Ape or a Monkey. Whenever Kibo attacks, defending player sacrifices an artifact of their choice.

Complete guide

Kibo, Uktabi Prince is a unique commander that blends diplomacy with aggressive primate tribal synergy. By handing out delicious Banana tokens to your opponents, you set the stage for your Apes and Monkeys to grow stronger whenever those artifacts are consumed or destroyed.

Generous Gifts and Primate Growth

Kibo has three distinct abilities. First, he can tap to give every player a Banana token. Second, he triggers whenever an opponent's artifact is put into a graveyard from the battlefield, granting +1/+1 counters to all your Apes and Monkeys. Finally, he forces the defending player to sacrifice an artifact whenever he attacks. This creates a loop where you provide the artifacts that fuel your creatures' growth.

Resolving the Banana Economy

When you activate Kibo's first ability, every player (including you) creates a Banana token. These tokens are artifacts that can be sacrificed for red or green mana and 2 life. Crucially, Kibo's second ability triggers regardless of how an opponent's artifact reaches the graveyard—whether they sacrifice the Banana for mana, you destroy it with a spell, or it is sacrificed during Kibo's attack phase, your primates will receive counters.

Common Pitfalls

A common mistake is forgetting that Kibo's growth trigger applies to ALL Apes and Monkeys you control, not just Kibo himself. Also, remember that the artifact must hit the graveyard from the battlefield. If an artifact is exiled instead of destroyed, or if it is discarded from a hand, Kibo's second ability will not trigger. Lastly, the sacrifice on attack is the defending player's choice, so they will likely choose their least valuable artifact or a Banana you recently gave them.

Strategic Timing

The best time to activate Kibo's tap ability is often during your own turn before you attack. This ensures the defending player has an artifact to sacrifice to Kibo's attack trigger if they don't have others. However, holding the ability until an opponent's end step can also be wise if you want to keep Kibo as a potential blocker or wait to see if they need the mana.

Interaction examples

The Banana Sacrifice

You tap Kibo to give yourself and your opponent a Banana. On your opponent's turn, they sacrifice the Banana to add one Green mana. Because an artifact an opponent controlled was put into a graveyard from the battlefield, Kibo's triggered ability goes on the stack. When it resolves, Kibo (and any other Apes or Monkeys you control) gets a +1/+1 counter.

Attacking into Artifact Creatures

Solemn Simulacrum

You attack an opponent who controls a Solemn Simulacrum. Kibo's attack trigger forces them to sacrifice an artifact. They choose to sacrifice the Solemn Simulacrum. Two things happen: the opponent's Simulacrum 'dies' trigger goes on the stack, and Kibo's counter-adding trigger also goes on the stack. Your Apes and Monkeys grow, and your opponent draws a card.

Non-Artifact Interactions

Sakura-Tribe Elder

If your opponent sacrifices Sakura-Tribe Elder to find a land, Kibo does not trigger. Even though a permanent was put into an opponent's graveyard, Kibo specifically checks for the 'Artifact' type. Since Sakura-Tribe Elder is only a 'Creature — Snake Shaman', it does not provide counters to your primates.
