Quandrix Command | Instant | | Choose two — • Return target creature or planeswalker to its owner's hand. • Counter target artifact or enchantment spell. • Put two +1/+1 counters on target creature. • Target player shuffles up to three target cards from their graveyard into their library. | Viktor Titov

Manifestation Sage | Creature | Human Wizard | When Manifestation Sage enters the battlefield, create a 0/0 green and blue Fractal creature token. Put X +1/+1 counters on it, where X is the number of cards in your hand. | Darren Tan

Double Major | Instant | | Copy target creature spell you control, except it isn't legendary if the spell is legendary. (A copy of a creature spell becomes a token.) | Suzanne Helmigh

Codie, Vociferous Codex | Legendary Artifact Creature | Construct | You can't cast permanent spells. {4}, {T}: Add {W}{U}{B}{R}{G}. When you cast your next spell this turn, exile cards from the top of your library until you exile an instant or sorcery card with lesser mana value. Until end of turn, you may cast that card without paying its mana cost. Put each other card exiled this way on the bottom of your library in a random order. | Daniel Ljunggren

Vineglimmer Snarl | Land | | As Vineglimmer Snarl enters the battlefield, you may reveal a Forest or Island card from your hand. If you don't, Vineglimmer Snarl enters the battlefield tapped. {T}: Add {G} or {U}. | Sam Burley
