"Until this expedition is done, that blade is your guardian, your liberator, and your best friend all rolled into one." —Yon Basrel, Oran-Rief survivalist
Secret council — Each player secretly votes for truth or consequences, then those votes are revealed. You draw cards equal to the number of truth votes. Then choose an opponent at random. Truth or Consequences deals 3 damage to that player for each consequences vote.
Target opponent chooses one — • Truth — That player plays with their hand revealed for the rest of the game. • Dare — Mill all but the bottom ten cards of that player's library. (To mill, put the top card of that library into its owner's graveyard.)
Reveal the top five cards of your library and separate them into two piles. An opponent chooses one of those piles. Put a card from the chosen pile into your hand, then put all other cards revealed this way on the bottom of your library in any order.
Choose a creature type. Target player reveals their hand and discards all creature cards of that type. Then destroy all creatures of that type that player controls. They can't be regenerated.
Players play a subgame starting at 5 life and with up to three permanent cards with different names from their main-game library on the battlefield. As the subgame ends, the winner chooses one of the cards they put onto the battlefield as the subgame began and puts it onto the battlefield rather than shuffling it into their library.
Tundra Fumarole deals 4 damage to target creature or planeswalker. Add {C} for each {S} spent to cast this spell. Until end of turn, you don't lose this mana as steps and phases end.
The only thing that smells worse than troll is burnt troll.
Choose a card name. Target player reveals cards from the top of their library until a card with that name is revealed. If it is, that player puts the rest of the revealed cards into their graveyard and puts the card with the chosen name on top of their library. Otherwise, the player shuffles.
Visit — Choose an opponent. They choose a creature they control, then you choose a creature you control. You may exile the chosen creatures. If you do, return them to the battlefield under their owners' control at the beginning of the next end step. Otherwise, the chosen creatures fight each other.
When Turf War enters, for each player, put a contested counter on target land that player controls. Whenever a creature deals combat damage to a player, if that player controls one or more lands with contested counters on them, that creature's controller gains control of one of those lands of their choice and untaps it.
