3 rulings from Wizards of the Coast
- 7 June 2024Rampant Frogantua's second ability counts players who lost the game before Rampant Frogantua entered the battlefield.
- 7 June 2024If the number of cards remaining in your library is less than the amount of combat damage dealt to a player by Rampant Frogantua, you can't choose to mill that many cards with Rampant Frogantua's last ability.
- 7 June 2024Rampant Frogantua's second ability counts every player who has lost, no matter how the player lost the game: due to a state-based action (having 0 or less life, trying to draw a card from an empty library, having 10 or more poison counters), because of a spell or effect that states they lose the game, because your awesome might has left them with no choice other than concession, or for any other reason.
