Kato the Arm

Q: Can Kato the Arm give himself his own Might and keywords?

"Friendly unit" does properly include Kato himself, but that wasn't the intent behind this card-Kato can't throw himself, after all. It was a simple goof that Kato made it out the door without the word "another," and the gameplay is so divergent from the design intent that we're changing it to fix this error.

Q: Does Kato give keywords he's gained during play? What about Might bonuses from various sources like Equipment?

Yes. Kato gives his current keywords and additional Might equal to his current Might to the unit you choose. Later changes to Kato don't matter; what the unit gets is locked in as the ability resolves.

Riftbound Core Rules (2026-07-16)

761.2. 2. Identifying a combination of traits and characteristics that can identify that card uniquely. Example: "The blue Kai'Sa," "the 6 [M] Kai'Sa" or "the [6] Energy Kai'Sa" are sufficient to identify Kai'Sa, Evolutionary when there are no other cards that satisfy those traits. Example: If there is only one unit with Kato in their name, saying "Kato" is sufficient to identify the card in question even if the exact name of the card is "Kato the Arm."
