Maelstrom Muse | Creature | Djinn Wizard | Flying Whenever Maelstrom Muse attacks, the next instant or sorcery spell you cast this turn costs {X} less to cast, where X is Maelstrom Muse's power as this ability resolves. | Michele Parisi

Elemental Expressionist | Creature | Orc Wizard | Magecraft — Whenever you cast or copy an instant or sorcery spell, choose target creature you control. Until end of turn, it gains "If this creature would leave the battlefield, exile it instead of putting it anywhere else" and "When this creature is put into exile, create a 4/4 blue and red Elemental creature token." (Each instance of that ability triggers separately.) | Zack Stella

Galazeth Prismari | Legendary Creature | Elder Dragon | Flying When Galazeth Prismari enters the battlefield, create a Treasure token. Artifacts you control have "{T}: Add one mana of any color. Spend this mana only to cast an instant or sorcery spell." | Raymond Swanland

Eureka Moment | Instant | | Draw two cards. You may put a land card from your hand onto the battlefield. | Anna Steinbauer

Quandrix Cultivator | Creature | Turtle Druid | When Quandrix Cultivator enters the battlefield, you may search your library for a basic Forest or Island card, put it onto the battlefield, then shuffle. | Filip Burburan

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
