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

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

Rushed Rebirth | Instant | | Choose target creature. When that creature dies this turn, search your library for a creature card with lesser mana value, put it onto the battlefield tapped, then shuffle. | Jason Kang
