Menace Whenever Sheoldred's Assimilator enters or attacks, exile up to one target card from a graveyard. If a card is exiled this way, you may conjure a duplicate of that card into the top five cards of your library at random.
If an opponent has more life than you, you gain 4 life. If an opponent controls more creatures than you, create two 1/1 white Human creature tokens. If an opponent has more cards in hand than you, draw a card.
Destroy up to X target artifacts and/or enchantments. Create twice X 1/1 black and green Pest creature tokens with "When this token dies, you gain 1 life."
A thousand years of history undone by one juvenile prank.
Whenever one or more creatures you control deal combat damage to a player, you may sacrifice one of them. If you do, reveal cards from the top of your library until you reveal a creature card that shares a creature type with the sacrificed creature. Put that card onto the battlefield and the rest on the bottom of your library in a random order.
Choose a creature type. Coordinated Barrage deals damage to target attacking or blocking creature equal to the number of permanents you control of the chosen type.
Flying Whenever Mirko Vosk deals combat damage to a player, that player reveals cards from the top of their library until they reveal four land cards, then puts those cards into their graveyard.
Flying Vrestin enters with X +1/+1 counters on it. When Vrestin enters, create X 1/1 green and white Alien Insect creature tokens with flying. Whenever you attack with one or more Insects, put a +1/+1 counter on each of them.
This artifact doesn't untap during your untap step. {4}, {T}: This artifact deals 2 damage to any target. At the beginning of your upkeep, you may discard a card. If you do, untap this artifact.
Enlist Whenever Benalish Knight-Counselor enlists a creature, you get a one-time boon with "When you cast a creature spell, that creature enters with a +1/+1 counter on it."
This spell costs {2} less to cast if it targets a black permanent. Bouncer's Beatdown deals X damage to target creature or planeswalker, where X is the greatest power among creatures you control. If that creature or planeswalker would die this turn, exile it instead.
As this artifact enters, choose a color. Creatures of the chosen color get +1/+1. Whenever a basic land is tapped for mana of the chosen color, its controller adds an additional one mana of that color.
