Kudo, King Among Bears

• WWizards of the Coast2024-06-07
  Official Ruling
  Kudo, King Among Bears's ability overwrites any effects that set a creature's power and toughness. Any existing effects or counters that raise, lower, or switch a creature's power and/or toughness continue to apply to the creature's newly set power and toughness. Any power- or toughness-setting effects that start to apply after Kudo enters the battlefield will overwrite this effect.

  Official Ruling
  If an effect causes a noncreature permanent to become a creature and sets its power and toughness as it does so, that creature will have that power and toughness; it won't be 2/2. Notably, crewing a Vehicle does not set its power and toughness, so a Vehicle will be a 2/2 creature once crewed.

  Official Ruling
  Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to creatures may become lethal if Kudo enters or leaves the battlefield during that turn.
