"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.
Flying Commander spells you cast have demonstrate. (When you cast a commander spell, you may copy it. If you do, choose an opponent to also copy it. The copies become tokens.) The "legend rule" doesn't apply to commanders you control.
Subterranean Assault — Whenever Trygon Prime attacks, put a +1/+1 counter on it and a +1/+1 counter on up to one other target attacking creature. That creature can't be blocked this turn.
The walls of the Necron tomb were unbreakable. The ground beneath it was not.
Partner with Silvar, Devourer of the Free At the beginning of your end step, if you attacked this turn, create a 1/1 white Human Soldier creature token.
{T}: Destroy target creature if it shares a color with the most common color among all permanents or a color tied for most common. A creature destroyed this way can't be regenerated.
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.
Whenever Tuktuk Scrapper or another Ally you control enters, you may destroy target artifact. If that artifact is put into a graveyard this way, Tuktuk Scrapper deals damage to that artifact's controller equal to the number of Allies you control.
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.
