  "narrative_beat": "Divine command turns the sea into a timed advance.",
  "design_note": "Pay three mana from any legal source when the attack trigger resolves. The wave is always three temporary Krakens, with no per-land counting. Triton grants trample immediately even when summoning-sick. Tokens enter attacking and do not trigger abilities requiring attackers to be declared. The sea withdraws at end of combat.",
